Description

Shifter for screwdriver and healing cap in mistaken swallowing and aspiration preventing implant system

Technical Field

The utility model belongs to oral medical instrument field especially relates to prevent mistake swallowing mistake and inhale the translator of screwdriver and healing cap in the implant system.

Background

The oral cavity diagnosis and treatment operation space is limited, the visual field is difficult, the diagnosis and treatment instruments are small and various and have different shapes, and due to the influence of factors such as saliva, blood, water spraying and the like, the oral cavity medical instruments are easy to fall off accidentally, so that the medical risk that the oral cavity medical instruments are mistakenly swallowed and inhaled into the body by a patient exists. According to investigation, the incidence rate of mistaking and aspiration of the oral cavity diagnosis and treatment instrument is 0.004%, mistaking and aspiration are obviously more than mistaking and are mostly generated in the middle-aged, the old and children. In the oral implantation repair diagnosis and treatment, a screwdriver, a covering screw and a healing cap are commonly used for sealing and connecting out an implant platform in first-stage and second-stage operations, and are also implant system components which are most easily swallowed and sucked by mistake.

The main reasons for accidental slippage and aspiration of these components are:

1. the tools of a screwdriver, a covering screw, a healing cap and the like of the planting system are small and exquisite, and a doctor is difficult to stably hold the implanting system after being stained with saliva and blood in the mouth of a patient;

2. the upper jaw area is operated against the gravity direction, and the components are easy to slide and fall;

3. the left maxillary posterior dental area has narrow visual field and insufficient light source, and the medical operation is sometimes in a blind vision state;

4. when adjacent teeth, bones or soft tissues are blocked, the stability of the connection mode of only depending on the frictional embedding of the tip of the screwdriver and the screw port of the healing cap/covering screw is insufficient, and the healing cap/covering screw is easy to loosen when contacting with a blocking body;

5. some doctors use tweezers to clamp the components, so that the stability is insufficient;

6. the patient is not matched, and the head moves too much;

7. systemic disease in the patient results in a weakening of the protective swallowing and coughing reflexes;

8. tired operation by doctors;

9. after the fall out of the device occurs, the fear response of the patient makes removal of the falling device difficult.

The slipping part can be sucked into the trachea or swallowed into the alimentary canal, so that digestive tract symptoms such as swallowing pain and swallowing difficulty of a patient and respiratory tract symptoms such as dyspnea and cough are caused; meanwhile, small and sharp components can also wander away in the body to further scratch tissues, so that serious medical accidents such as perforation, heavy bleeding and even life threatening are caused. Research shows that once these mistaking and mistaking events occur, most of them need endoscope or even open operation to be taken out, which results in serious doctor-patient trust crisis or medical dispute, brings great threat to physical and mental health of patients, and brings great loss in occupation, industry reputation and economy to doctors and hospitals. Therefore, prevention of aspiration by mistake of these small parts is of great importance in the clinic, and prevention itself is the best treatment.

Unfortunately, although physicians are aware of the dangers of aspiration by mistake, current prevention still relies on careful manipulations and aspiration. This is particularly insufficient in the above-mentioned adverse situations, and the erroneous swallowing and sucking still occur. Therefore, from the physical mechanics aspect utility model a device that is used for fixing in advance and realizes whole transfer inside and outside patient's oral cavity, come to fix, stabilize and safely transfer parts such as screwdriver, healing cap/cover screw to avoid the unexpected pine of planting the apparatus to take off and by the emergence of the medical malpractice that the patient swallowed the mistake and inhaled.

The utility model discloses a realize through following technical scheme:

the shifter for the screwdriver and the healing cap in the mistaken swallowing and sucking preventing implant system comprises a fixed cover body and a clamping sleeve which are detachably connected; the top surface of the fixed cover body is provided with a fixing hole for the screwdriver handle to penetrate through; the inner cavity of the clamping sleeve is provided with a clamping component for clamping a healing cap/covering screw; the fixing hole is communicated with the inner cavity of the clamping sleeve, so that the screwdriver can be matched with the healing cap/covering screw clamped by the clamping assembly.

By the proposal, the utility model discloses at least, obtain following technological effect:

the screwdriver is inserted into the fixing hole in the fixing cover body, so that the effect of stable installation is formed, and the screwdriver is not easy to fall off; then the healing cap/cover screw is placed into the inner cavity of the clamping sleeve from the pipe orifice of the clamping sleeve and is clamped and fixed through the built-in clamping assembly. The fixing hole is communicated with the inner cavity of the clamping sleeve, so that the tip of the screwdriver can be in contact matching with a screw port at the top of the healing cap/covering screw.

In clinical operation, the screwdriver and the healing cap/covering screw are arranged on the translator outside the oral cavity of a patient according to the scheme, and then the translator system is integrally transferred to the implant platform in the oral cavity. The healing cap/cover screw is screwed by the screwdriver, and the clamping assembly can be unlocked to release the healing cap/cover screw during screwing so as to avoid the influence of the clamping assembly on screwing operation. After screwing the healing cap/cover screw, the transfer device is moved out of the oral cavity, and the screwdriver is fixed and taken out.

The shifter can be used for stable retention and shifting of components of a screwdriver, a healing cap/a covering screw and other planting systems, and avoids the risk that instruments fall off and are mistakenly swallowed and sucked in clinical diagnosis and treatment, so that the high-efficiency safety of the clinical diagnosis and treatment and the physical and psychological health of patients are practically guaranteed.

Preferably, the fixed cover body is in an elliptic cylinder shape, two ends of a long shaft of the elliptic top surface of the fixed cover body are symmetrically provided with rope penetrating holes, and a traction rope is matched in the rope penetrating holes.

The fixed cover body is in an elliptic cylinder shape, and when the fixed cover body is placed in the oral edentulous gap, the long axis of the ellipse is vertical to the plane of the edentulous gap (namely, the fixed cover body is placed in the buccolingual direction). In clinical operation, one end of the traction rope can be knotted at the protruding end after passing through the threading hole; the other end of the traction rope is tied to the working wrist of the doctor. Or, the two ends of the traction rope are hijacked and connected to form a rope sleeve, the translator is fixed in a similar mode of stringing and knotting a rope through a stringing hole of a mobile phone, and the other end of the traction rope is sleeved at the working wrist of a doctor to prevent the translator from integrally falling off.

Preferably, the clamping assembly comprises two clamping arms which are symmetrically arranged; any clamping arm comprises a rubber clamping piece and a telescopic key; the rubber clamping piece is arranged in the inner cavity of the clamping sleeve, one end of the telescopic key penetrates through a window formed in the side wall of the clamping sleeve and is detachably connected with the rubber clamping piece, and the other end of the telescopic key protrudes out of the side wall of the clamping sleeve.

The symmetrical clamping arm structure can clamp and fix the healing cap/cover screw from two sides. The retractable key is similar to a clamping 'switch button', and the clamping/releasing action of the clamping component can be controlled by pressing/releasing. The two sides of the shifter are symmetrically pressed with the projecting telescopic parts, the pressing force is transferred to the rubber clamping piece, and the rubber clamping piece is pressed against the side wall of the healing cap/covering screw. The rubber clamping pieces made of rubber materials are elastically deformed under stress, the contact area between the rubber clamping pieces and the side wall of the healing cap/covering screw is increased, and under the combined action of the friction coefficient and the contact area of the rubber materials and the pressure generated by pressing, the friction force between the rubber clamping pieces on the two sides and the side wall of the healing cap/covering screw is larger than the gravity of the healing cap/covering screw, so that the clamping effect is realized. And the larger the contact area is, the stronger the pressure is, the larger the generated friction force is, the higher the stability of clamping the healing cap/covering screw is, and the loosening of the healing cap/covering screw in the transferring process is avoided.

Preferably, the telescopic key comprises a first connecting rod, a second connecting rod and a key; the first connecting rod and the second connecting rod are parallel to each other, one ends of the first connecting rod and the second connecting rod, which are positioned in the inner cavity of the clamping sleeve, are connected with the rubber clamping piece, and one ends of the two connecting rods, which protrude out of the side wall of the clamping sleeve, are vertically connected with the keys; one end of the key connected with the first connecting rod protrudes to form an upper edge; a tooth groove is formed in the rod body of the second connecting rod, a convex tooth is formed on the inner side wall of the window matched with the second connecting rod, and the tooth groove is meshed in the convex tooth.

If the clamping assembly has no locking structure, a doctor always needs to press the telescopic key to keep the clamping force on the clamping piece, so that the stable clamping and the looseness prevention of the healing cap/the covering screw are ensured. However, when moving the distractor into the patient's mouth, it is difficult for the fingers of the surgeon to enter the narrow edentulous space along with the distractor and maintain a stable posture. Therefore, a locking structure is arranged on the telescopic key to fix the position of the clamping arm, and a stable clamping effect is provided.

The locking structure comprises tooth grooves formed in the second connecting rod and convex teeth formed in the side wall of the corresponding window, and the tooth grooves and the convex teeth are meshed with each other to generate the effect of locking the second connecting rod. Or when the thickness of the side wall of the clamping sleeve is not enough, the tooth grooves can directly abut against the inner side wall of the clamping sleeve to realize the effect of locking the second connecting rod.

The unlocking structure is a protruded upper edge of the key. By pressing the upper edge part, the first connecting rod and the second connecting rod are inclined in a small range in the corresponding window, the tooth grooves in the second connecting rod are separated from the convex teeth, and the limiting effect of the second connecting rod is relieved. The whole telescopic piece can be manually pulled out for a certain distance, and the rubber clamping piece is separated from the healing cap/the covering screw to realize the releasing function.

For further reinforcing the supporting effect of flexible key to the rubber clamping piece, first connecting rod and second connecting rod are connected with the rubber clamping piece simultaneously, promote stability through two strong points.

Preferably, any one of the clamping arms further comprises a return spring; one end of the reset spring is connected with the key, and the other end of the reset spring is connected with the side wall of the clamping sleeve.

If the clamping assembly has no unlocking structure, the doctor is difficult to efficiently reset the initial position of the clamping piece after pressing the clamping, and therefore the clamping arm needs to be pulled out for an additional manual resetting process. This reset operation is clearly inefficient and inaccurate. Therefore, the reset spring is additionally arranged between the key and the side wall of the clamping sleeve, so that the telescopic key can be automatically ejected after unlocking, the situation that the tooth socket on the second connecting rod is meshed with the convex tooth on the inner side wall of the window again to form limiting locking after the upper edge of the key is pressed for unlocking is avoided,

when the screw is unlocked, the upper edge of the key is pressed, so that the first connecting rod and the second connecting rod generate small-amplitude upward displacement in the window, the tooth socket on the second connecting rod is disengaged from the convex tooth on the inner side wall of the window, and the elastic restoring force of the return spring drives the clamping arm to return to the initial position of the clamping arm, so that the effects of unlocking and releasing the healing cap/covering screw are realized.

Preferably, the top cross section of the rubber clip is arc-shaped, and the central angle of the orthographic projection arc of the rubber clip in the top surface of the fixed cover body is greater than or equal to 90 degrees and less than 180 degrees.

Because the sizes of the healing caps/the covering screws of different models are different, in order to improve the applicability of the transfer device, the circular-arc rubber clamping pieces are adopted to clamp the healing caps/the covering screws. Because the two rubber clamping pieces in the two symmetrical clamping arms are also in mirror image structures, the shapes of the two rubber clamping pieces are limited between a quarter arc and a half arc.

If the radian of the two rubber clamping pieces is too large, the edges of the two rubber clamping pieces are mutually extruded to influence the clamping effect when the healing cap/covering screw with a smaller diameter is clamped.

If the radian of the two rubber clamping pieces is too small, when the healing cap/covering screw with a larger diameter is clamped, the contact area between the two rubber clamping pieces and the edge of the healing cap/covering screw is insufficient, so that the healing cap/covering screw is shaken and loosened.

Preferably, the side wall of the clamping sleeve is stepped; the top pipe orifice of the clamping sleeve is detachably embedded into the bottom cover orifice of the fixed cover body.

The clamping sleeve and the fixed cover body are connected in a detachable embedded mode, and the reduction of the fixed structure is beneficial to reducing the volume of the transfer device; meanwhile, dead angles which are difficult to clean and disinfect in the transfer device are reduced, so that the transfer device is cleaned and disinfected more thoroughly, and medical cross infection is avoided.

The clamping sleeve is smoothly connected with the fixed cover body in appearance, and the whole shifter is smooth and has no edges and corners, so that the oral cavity of a patient can be prevented from being scratched. Therefore, in order to meet the embedded connection requirement, the side wall of the clamping sleeve is arranged to be in a step shape, and the narrow opening is embedded into the fixed cover body.

Preferably, the fixed cover body is made of medical rubber; and the inner diameter of the fixing hole is smaller than the diameter of the screwdriver handle.

In order to facilitate disinfection and cleaning, the fixed cover body is made of medical rubber. The rubber material of the fixed cover body has a dual function: firstly, the elastic deformation of the rubber enables the cover body to be embedded with the clamping sleeve; secondly, the elastic deformation capability can also make the fixed hole have the effect of expanding and contracting. The diameter of the fixing hole is slightly smaller than the diameter of the screwdriver handle, when the screwdriver handle penetrates through the fixing hole, the side wall of the fixing hole is stressed and deformed to extrude and fix the screwdriver handle, and therefore the mounting stability of the screwdriver is improved.

Preferably, the thickness of the top of the fixed cover body is 20-40% of the length of the screwdriver handle fixed by the fixed cover body.

In order to further enhance the stabilizing effect, the fixing cover body needs to have a certain thickness to ensure the length of the fixing hole, so that the fixing channel has a sufficient contact area and forms a supporting effect. Therefore, the thickness of the top of the fixed cover body is limited to 20-40% of the length of the screwdriver shank. Too thin may affect the mounting stability of the screwdriver, and too thick may increase the volume of the shifter and affect the operation.

The utility model has the advantages that: the screwdriver and the healing cap/the covering screw are integrally installed outside the oral cavity of the patient through the transfer device, so that the screwdriver and the healing cap/the covering screw are prevented from loosening and falling in the process of moving into/out of the oral cavity of the patient, and the serious medical accidents and disputes caused by the fact that the screwdriver and the healing cap/the covering screw are further swallowed by the patient by mistake and inhaled into the body by mistake are prevented. The utility model discloses a device is showing high efficiency, the security that has strengthened the transfer operation in planting clinical art, has ensured patient's physical and mental health conscientiously. In addition, the transfer device has the advantages of relatively simple structure, low cost, simple clinical operation, detachable and replaceable accessories, convenient maintenance, medical disinfection and the like, and can be recommended to be configured and used as an accessory of the surgical tool box of the oral implant system.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1:

as shown in fig. 1-8, the shifter for the screwdriver and the healing cap in the mis-swallowing and mis-sucking prevention implant system comprises a fixed cover body 1 and a clamping sleeve 2 embedded at the bottom of the fixed cover body 1; the top surface of the fixed cover body 1 is provided with a fixed hole 11 communicated with the inner cavity of the clamping sleeve 2; the inner cavity of the clamping sleeve 2 is provided with a clamping component 21; the screwdriver 3 penetrates into the inner cavity of the clamping sleeve 2 through the fixing hole 11; the healing cap/cover screw 4 is put into the inner cavity of the clamping sleeve 2 from the port of the clamping sleeve and is clamped and fixed through the clamping component 21; the tip of the screwdriver 3 in the inner cavity can be contacted and matched with a screw port at the top of the healing cap/covering screw 4; the screw driver 3 and the healing cap/covering screw 4 are integrally combined on the transfer device outside the oral cavity of the patient and then integrally moved into the oral cavity of the patient, the screw driver 3 is operated to pre-screw the healing cap/covering screw 4 onto the implant platform in the state of being clamped by the transfer device, after the healing cap/covering screw 4 is released by the unlocking clamping assembly 21, the healing cap/covering screw 4 is continuously screwed, the transfer device is taken out, and the screw driver 3 is fixedly taken out together. Thereby realizing the transfer effect of the device-free loosening and falling.

Wherein, the clamping assembly 21 comprises two clamping arms which are symmetrically arranged. Any clamping arm is composed of a rubber clamping piece 211, a telescopic key 212 and a return spring 213; the telescopic key 212 includes a first link 2121, a second link 2122, and a key 2123.

Two groups of windows 22 are symmetrically arranged on the side wall of the clamping sleeve 2, each group of windows 22 is two, the first connecting rod 2121 and the second connecting rod 2122 of each clamping arm on each side respectively penetrate through the two windows 22 on the same side to be detachably connected with the rubber clamping piece 211 in the inner cavity of the clamping sleeve 2, and meanwhile, the first connecting rod 2121 and the second connecting rod 2122 are simultaneously and vertically connected with the key 2123. The two connecting rods form a stable supporting effect on the rubber clamping piece 211, so that the pressure applied to the whole telescopic key 212 is conveniently transmitted to the rubber clamping piece 211. By pressing the telescopic keys 212 on both sides of the clamping sleeve 2, the rubber clamping pieces 211 on both sides can clamp and fix the healing cap/cover screw 4 from both sides thereof, respectively.

The locking structure of the telescopic key 212 is a spline 2124 formed on the second link 2122 and protruding teeth 221 formed on the inner side wall of the window 22, and the protruding teeth 221 and the spline 2124 are engaged with each other. When the key 2123 is pressed to press the first and second connecting rods 2121 and 2122 into the inner cavity of the clamping sleeve 2, the tooth groove 2124 of the second connecting rod 2122 engages with the convex tooth 221 on the inner side wall of the window 22 to generate a locking effect, so as to limit the movement of the second connecting rod 2122 in the direction extending out of the clamping sleeve 2, thereby keeping the rubber clamping piece 211 fixed by the double-sided connecting rod in a stable clamping state.

The unlocking structure of the telescopic key 212 is an upper edge of the key 2123 extending outward at the connection end of the first link 2121. Pressing the upper edge of the button 2123 makes the first link 2121 and the second link 2122 incline slightly within the window 22, so that the tooth groove 2124 of the second link 2122 is separated from the contact with the convex tooth 221 on the inner side wall of the window 22, and after the double-sided link is pulled out manually, the rubber clip 211 connected with the link returns to the original position and is separated from the contact with the healing cap/cover screw 4, thereby releasing the clamping effect.

The reset effect of the telescopic key 212 is that two ends of the reset spring 213 are respectively connected with the key 2123 and the side wall of the clamping sleeve 2, and when the telescopic key 212 is in the locking state, the reset spring 213 is in the compressed state. When the upper edge of the button 2123 is pressed to unlock, as the teeth 2124 of the second link 2122 are disengaged from the teeth 221 on the inner sidewall of the window 22, the elastic restoring effect of the restoring spring 213 ejects the button 2123 away from the clamping sleeve 2, and the two rubber clips 211 are separated from the healing cap/cover screw 4, thereby releasing the clamping effect and restoring the clamping assembly 21 to its initial position.

Example 2:

as shown in fig. 1-8, the transfer device is a recyclable medical device that is inserted into the patient's mouth. In order to facilitate the cleaning and disinfection in medical treatment and simultaneously achieve more gain effects, the material of the diverter is improved on the basis of not changing the scheme of the embodiment 1:

the fixed cover body 1 is made of medical rubber, so that the fixed cover body can still keep relatively stable physicochemical characteristics under the high-frequency sterilization and disinfection state. In addition, the medical rubber material can also provide a proper amount of elastic deformation, which is beneficial to the embedding of the fixed cover body 11 and the clamping sleeve and is also beneficial to improving the constraint force on the screwdriver 33.

The size of the hole diameter of the fixing hole 1111 is designed to be smaller than the diameter of the shank of the screwdriver 3. The inner wall of the fixing hole 11 has the effect of squeezing and clamping the handle of the screwdriver 3, and the stability of the screwdriver 3 mounted on the transfer device is enhanced.

It is worth mentioning that the top of the fixed cover body 1 is partially thickened to be more than 20% of the length of the handle of the screwdriver 3, so that the constraint effect of the fixed hole 11 on the screwdriver 3 can be improved to the maximum, and the screwdriver 3 can be prevented from swinging; however, thickening beyond 40% can result in a diverter that is too bulky to operate.

The rubber clip 211 is also made of medical rubber. The elastic effect of the rubber clip 211 can increase its attachment area with the healing cap/cover screw 4, enhancing friction, thereby enhancing the clamping effect.

The clamping sleeve 2 is made of medical metal materials, and the clamping sleeve 2 needs to be used as a support body of the telescopic key 212, so that the structural strength of the clamping sleeve is kept, and deformation is avoided, so that the medical metal materials are most suitable. Not only can no serious oxidation corrosion be caused by high-frequency sterilization and disinfection operation, but also enough structural strength can be provided to support the locking effect of the telescopic key 212.

The first link 2121, the second link 2122 and the key 2123 of the telescopic key 212 are made of the same medical metal material, so as to: the requirements of sterilization and disinfection are met; a stable supporting rubber clip 211; without the formation of galvanic effect and without chemical corrosion.

Example 3:

as shown in fig. 1 to 8, on the basis of not changing embodiment 1 or embodiment 2, in order to prevent the whole shifter from loosening and falling into the patient's mouth, the whole shifter needs to be designed to be anti-loosening.

The fixed cover body 1 is designed into an elliptic cylinder shape, so that the fixed cover body is convenient to be attached and placed in the gap of the missing teeth in the mouth. Two ends of the long axis of the elliptic top surface of the elliptic cylinder are provided with rope through holes 12, a traction rope 5 can be tied in the rope through holes 12, and the other end of the traction rope 5 is sleeved on the working wrist of a doctor so as to prevent the whole transfer device from falling. Or the traction ropes 5 are connected end to form a rope sleeve, one part is fixed in the rope penetrating hole 12, and the other part is sleeved on the working wrist of the doctor in a surrounding manner, so that the whole transfer device is prevented from falling.

Example 4:

as shown in fig. 1 to 8, the rubber clip 211 is arc-shaped to improve the clamping effect of the rubber clip 211 on the healing cap/cover screw 4 without changing embodiment 1, embodiment 2 or embodiment 3. In order to more clearly describe the shape of the rubber clip 211, the rubber clip 211 is projected to the top surface of the stationary cover 1 for description.

The orthographic projection of the two rubber clamping pieces 211 on the top surface of the fixed cover is two arcs, and the length of the arc is determined by the angle of the circle center of the arc and the diameter of the arc. Therefore, the central angle thereof is defined to be greater than or equal to 90 ° and less than 180 °. The single arc is kept between a quarter arc and a half arc. The phenomenon that the arc lengths are too large to cause the arcs at the two ends which are mirror images to extrude and coincide with each other at the edge is avoided.

Taking the zeeman planting system as an example, the largest model of a typical healing cap/cover screw is 7mm in diameter. In order to ensure the contact area between the two rubber clamping pieces and the edge of the 7mm healing cap/covering screw to improve the stability, the two rubber clamping pieces are in a structure with two half arcs and an inner diameter of 7mm, and the two rubber clamping pieces are buckled from two sides to form a circular ring to wrap the healing cap/covering screw. Or, the two rubber clamping pieces are in a structure that the shape of the rubber clamping pieces is a quarter of a circular arc and the inner diameter of the rubber clamping pieces is larger than 7mm, and the two rubber clamping pieces clamp the healing cap/the covering screw from two sides.

In order to facilitate detachable connection of the rubber clamping piece 211, the ends of the first connecting rod 2121 and the second connecting rod 2122 are respectively provided with a tenon 2125, and the back surface of the rubber clamping piece 211 is provided with a tenon hole 2111 corresponding to the connection position of the first connecting rod 2121 and the second connecting rod 2122, so that the tenon 2125 at the end of the first connecting rod 2121 and the tenon 2125 at the end of the second connecting rod 2122 can be respectively inserted into the two tenon holes 2111 of the rubber clamping piece 211.
