Description

Glove port laparoscopic surgery device

Technical Field

The invention relates to a glove port instrument for a glove port laparoscopic surgery. More specifically, the structure of the part requiring the guidance of the insertion of the tool during the operation or the operation is improved to be constituted by a one-handed cuff, so that the gas accumulated on the abdominal wall can be prevented from being discharged, and the occurrence of collision or noise (noise) around the insertion part can be reduced.

Background

Generally, the laparoscopic surgery (or the minimal erosion surgery) in the abdominal cavity has the advantages that compared with the traditional laparotomy, the surgical opening (incision) is smaller, the healing wound after the surgery is not obvious, the appearance is attractive, the pain feeling during the surgery is light, the postoperative recovery is fast, and the daily life can be quickly recovered after the patient is in a hospital. The application range is wide, and the application of the medicine composition in partial tumor surgery is started recently.

When such a laparoscopic endoscopic operation is performed, a surgical tool called a needle for intubation is introduced into the abdominal region of a patient, a small hole is made in the abdominal region of the patient, one or more catheters are inserted into the patient, and various surgical instruments such as forceps, a pulling instrument, an organ extraction product, a catheter, an endoscope, and the like are placed into the operating site in the abdominal cavity through the catheters. The surgical instrument is used in various common surgical operations such as cholecystectomy, gallstone excision, hydrops bulge excision and the like.

However, recently, the above-mentioned introduction of a plurality of catheters or abdominal incision surgery is hardly used in order to reduce the scars left on the abdomen of a patient after the surgery and to accelerate the postoperative recovery. Almost no scar is left, and the endoscope operation is performed only on one part of the navel. When a hole is drilled at the navel part of a human body in the operation, the wound can be healed without easily visible scars when the patient recovers in the future. Since the wound is not easily visible after the operation, many people recently prefer to select the endoscopic operation in which only one hole is formed in the navel portion.

In recent years, when performing endoscopic surgery, a surgical glove port is provided at a surgical opening in order to safely introduce various surgical instruments into the surgical site through a single opening.

In contrast to the conventional surgical cuff product, korean patent No. 10-915882 shows that an endoscopic surgical instrument guide is provided at the incision of the navel part during endoscopic surgery, and a multi-branched lip valve (V1) is designed at one side part (102) of a main body (101) of the instrument to guide the insertion of various surgical instruments, as shown in fig. 1 (here, korean patent No. 1, which is not the present invention fig. 1). In the surgical instrument guide part (100), a gas control valve (V2) which can reduce the nitrogen gas entering is arranged on one branch of the part (102) so as to reduce the generation of abdominal distension. The outer side of the bottom surface of the main body (101) of the surgical tool guiding part (100) is provided with a side groove, and an elastic attachment ring (110) which can be tightly attached to the surgical hole is arranged in the variable groove. A support ring (120) is provided on the outer side of the attachment ring (110) in the axial direction of the main body (101) portion so as to wrap around and adhere to the overlapping portion of the inner side, and the main body (101) of the surgical instrument can be supported by being matched with the attachment ring (110) in correspondence to the thickness of the abdominal wall when the surgical instrument is inserted through the abdominal incision.

However, the conventional surgical cuff lip valve (V1) has a weak coupling force and is liable to fall off during surgery.

Meanwhile, the control force and the restraining force of the support ring and the adsorption ring which are vertically attached to the abdominal wall are weaker, so that the support ring and the adsorption ring are prone to falling off in the operation process, and the support ring can be pulled to cause injury to a patient in the process of taking down the operation sleeve after the operation is finished.

Meanwhile, because the part outside the waste extraction body generated in the operation is not separately arranged, when the waste is taken out from the body, the problem that the extirpated object or the tumor block enters the body again can occur, and even if the small part enters the human body again, the potential safety hazard of secondary injury can also be generated.

According to the comparison, the prior surgical cuffs have various problems, so that research and design of novel surgical cuffs are urgently needed.

Detailed Description

A glove port laparoscopic surgical device of the present invention is described in detail below with reference to FIGS. 1-10.

Example of embodiment 1

As shown in fig. 1 to 5, the cuff device for single-port surgery of embodiment 1 includes a cuff device body 10, a tool insertion portion 20, an abdominal wall fixing portion 30, an extraction portion 40 and a gas access portion 50.

The device body 10 is formed of a tubular structure having one closed end, and can be roughly divided into three parts: that is, it is composed of a sealing part 110 with one end sealed in the device body 10, an extension part 120 extending from the sealing part 110 to the outside, and an insertion fixing part 130 capable of ensuring stable fixation on the abdominal wall after insertion through the operation opening.

In this case, the sealing portion 110 is provided with a tool insertion portion 20, the extension portion 120 is provided with an extraction portion 40, and the insertion fixing portion 130 is provided with an abdominal wall fixing portion 30.

The device body 10 is made of a soft synthetic resin film which is harmless to the human body.

In the device body 10, the sealing portion 110, the extension portion 120 and the insertion fixing portion 130 are integrally formed, or the sealing portion 110 is separately formed and then integrally connected to the upper end of the extension portion 120.

The plurality of tool insertion sites 20 are provided on the sealing part 110 of the device body 10, and have a sealing structure for preventing air injected into the abdominal cavity from being discharged outside at will by inserting surgical instruments into the abdominal cavity during surgery.

As shown in fig. 3 and 4, the tool insertion site 20 includes an access tube 210 and a closure structure 220.

The inlet tube 210 is positioned at one side of the sealing part 110, has a fixed end and is formed of a protruding structure having a certain length, thereby ensuring an inlet space for surgical tools, etc.

In this case, the size of the access tube 210, for example, the length and diameter of the projection, may be variously sized for the access tube 210 inside one glove port 1 in consideration of the difference in the kinds of operations or the difference in the kinds of tools, which are made different in length and diameter.

In addition, the upper end of the inlet pipe 210 is extended outward by a certain length, and is designed with a fixing section 212 for securing the connection with the enclosing structure 220.

Meanwhile, in order to ensure a stronger fixation with the enclosing structure 220, at least one 1 st insertion hole 214 is designed on the fixing section 212.

The 1 st insertion hole 214 is formed according to the connection relationship between the closing structure 220 and the inlet pipe 210, and may be omitted according to the coupling relationship between the closing structure 220 and the inlet pipe 210.

Meanwhile, a recessed space 216 is formed at an upper end portion of the inlet pipe 210, i.e., at an inner side below the fixing section 212.

When the closing structure 220 is fixed at the upper end of the inlet pipe 210, the above-mentioned recessed space 216 may be omitted in the case where the outer circumference of the inlet pipe 210 and the outer circumference of the closing structure 220 do not protrude outward to form a space.

Meanwhile, the inlet tube 210 may be integrally formed when the sealing part 110 of the device body 10 is manufactured, or may be separately manufactured and then combined with the inlet tube 210 and the sealing part 110.

The sealing structure 220 is designed at the upper end of the inlet tube 210, and when the surgical instrument is placed in the abdominal cavity of a patient through the inlet tube 210 for surgery, the injected gas can be prevented from being discharged at will, and the sealing capability is provided.

As shown in fig. 3 and 4, the closure structure 220 includes a lip valve 222, an upper cover plate 224, a cushion bladder 226, and upper and lower retaining rings 228, 229.

The lip valve 222 forms a frame having a certain width at an upper end thereof, and forms a central portion inclined with a center below the frame, wherein the upper central portion has a cut-away state having a certain length, and the cut-away portion maintains a close contact state by its own elasticity, and even if the lip valve enters the tool through the central portion, the lip valve can maintain a state of being closely connected to an extension of the tool by its own elasticity, thereby minimizing gas discharge.

The lip valve 222 is provided at the upper end of the fixing section 212 of the apparatus body 10 on the frame, and fixed by upper and lower fixing rings 228 and 229, and the fixing section 212 is provided with an insertion hole at a position corresponding to the 1 st insertion hole 214.

It should be noted that the lip valve 222 is a common technique in a glove port device and will not be described in detail here.

The upper end cover plate 224 is disposed at the upper end of the lip valve 222 and serves as a seal to minimize exhaust gas during tool insertion.

An access hole 2242 is formed in the upper end cover plate 224 to facilitate insertion of a tool from the center.

The access holes 2242 are uniform with the diameter of the tool, or slightly smaller. The tool is inserted to ensure intimate contact between the extensions of the tool and to enhance the sealing capability, and the access hole 2242 is sized to ensure that the tool does not interfere with the performance of the procedure during insertion and removal.

Meanwhile, a plurality of protrusions 2244 having a certain depth are formed on the upper end surface of the upper end cover plate 224. The protrusion 2244 may ensure a minimum contact area when a tool is inserted through the entrance hole 2242, ensure free entrance, and may be omitted according to circumstances.

Further, on the extension of the upper end cover plate 224 described above, the second insertion hole 2246 is provided at the corresponding position of the fixing section 212 and the 1 st insertion hole 2242.

The 2 nd insertion hole 2246 may be omitted depending on the fixing conditions of the upper and lower end fixing rings 228 and 229.

The upper cover plate 224 is not limited to a plate shape, but is positioned at the upper end of the lip valve 222 to ensure that the gas discharge is reduced as much as possible when a tool is inserted, thereby ensuring that tools of various shapes and structures can be used.

The cushion air bag 226 is disposed at the outermost side of the tool insertion portion 20, and can minimize noise generated when the tool insertion portion 20 is in contact with and collides with the tool insertion portion, and prevent the tool insertion portion 20 from being arbitrarily moved due to the collision, thereby having a cushion effect.

A buffer zone 2262 having a predetermined size and capable of generating a predetermined space is provided inside the buffer airbag 226, and upper and

lower ends

2264 and 2266 having a predetermined length and protruding inward are provided at one end of the inside of the buffer zone 2262.

The buffer zone 2262 forms a certain buffer area by forming a certain space therein. The buffer band 2262 is made of a material having elasticity, so that a buffer space can be formed by itself without a complicated process such as additional inflation.

In addition, in order to minimize interference with adjacent tool insertion sites 20 or direct tool impact, the buffer zone 2262 has a height, i.e., the buffer zone 2262 is designed at a height from the upper end cap 224.

At least one reinforcing rib 2268 is provided on the inner side of the buffer zone 2262 to reinforce the strength.

The reinforcing ribs 2268 can reinforce the strength of the buffer zone 2262, and rapidly restore the elasticity thereof when the tool insertion portion 20 is collided with the contact, while minimizing damage such as tearing.

The upper and

lower ends

2264 and 2266 are formed with protrusions having a predetermined length on one side of the inside of the buffer zone and fixed by upper and lower end fixing rings 228 and 229, and the upper and

lower ends

2264 and 2266 are provided with a 3 rd insertion hole 2265.

Between the upper and

lower ends

2264 and 2266, the fixing section 212 is formed at the outer periphery of the lip valve 222 and the outer end of the upper end cover plate 224, and upper and lower fixing rings 228 and 229 are provided at the upper and lower ends to ensure stable fixing.

The upper and lower end fixing rings 228 and 229 are coupled to each other, and the closing structure 220 provided at the upper end portion of the inlet pipe 210 is coupled more stably.

In addition, as shown in fig. 4b, the cushion bladder 226 has a lower end fixing ring 229 disposed below the cushion bladder 226, and the cushion bladder 226 having a certain thickness can reduce noise and interference when colliding with the adjacent tool insertion portion 20. The fixing ring may secure the strength of the airbag 226, but the position is not necessarily fixed as shown in fig. 4, and may be provided in the lower half of the airbag 226 with the same thickness.

The upper end fixing ring 228 has a ring structure, and a plurality of fixing protrusions 2282 having a predetermined height are formed at a predetermined interval on a bottom surface thereof.

The lower end fixing ring 229 is formed in a ring shape and is disposed at a corresponding portion of the fixing projection 2282, and the 4 th insertion hole 2292 is formed to ensure a certain fixing function when the fixing projection 2282 is inserted.

The above-mentioned fixing projection 2282, and the 1 st to 4 th insertion holes 214, 2246, 2265, 2292 are all provided at the same position, achieving good coupling and fixing ability with each other.

Meanwhile, the above-described constituent relationship of the fixing projection 2282 of the upper end fixing ring 228 and the 4 th insertion hole 2292 of the lower end fixing ring 229 may be replaced with each other.

As shown in FIGS. 1 and 2, one of the plurality of tool insertion sites 20 is longer than the other tool insertion sites 20 and is provided with a camera port 22 to allow a camera to enter the interior of the abdominal cavity.

The abdominal wall fixing site 30 is provided on the insertion fixing section 130 of the device body 10. The device body 10 can be stably fixed when inserted through the surgical port.

As shown in fig. 5, the abdominal wall fixing site 30 includes a 1 st air bladder 310 located at the lowermost end of the apparatus main body 10 and a 2 nd air bladder 320 spaced apart from the 1 st air bladder 310. The No. 2 air bag 320 is located inside the abdominal wall of the patient, and depending on the position of the No. 1 air bag 310, the No. 1 and No. 2 air bags are filled with air to maintain the device body 10 in a well fixed state on the abdominal wall.

In order to ensure that the 1 st and 2

nd air bags

310 and 320 can be inflated from the outside, the 1 st and 2

nd inlet pipes

312 and 322 are provided on one side thereof, respectively.

In this case, to ensure that the air entering and exiting through the 1 st and 2

nd inlet pipes

312, 322 is well controlled, a valve is provided at the rear end thereof. The valve provides good control of both the incoming and outgoing air from the 1 st and 2

nd inlet pipes

312, 322.

Furthermore, the 1 st and 2

nd inlet pipes

312, 322 may be filled with air by means of a manual or automatic pump, which applies common technical principles and will not be described in detail here.

In this case, the 2 nd inlet tube 322 may not only inject air into the 2 nd air bag 320 located inside the abdominal wall, but also serve as a handle when the 2 nd air bag 320 is removed after the operation is completed.

An elastic ring 324 having elasticity is provided inside the 2 nd air bladder 320, and the elastic ring 324 is positioned inside the 2 nd air bladder 320, so that when the 2 nd air bladder 320 is placed inside the abdominal cavity of the patient, the 2 nd air bladder 320 can be expanded to the abdominal wall inside the abdominal cavity by the elasticity of the elastic ring 324, and a good fixed state can be maintained.

The extraction portion 40 is located on the extension portion 120 of the device body 10, so as to safely extract the object during the operation and prevent the secondary injury of the patient caused by the extraction.

The extraction portion 40 includes an opening 42 having a predetermined size formed at one side of the device body 10, an extraction wing 44 extended to a predetermined length at an outer circumference of the opening 42, and a clip 46 at one side of the extraction wing 44.

The opening 42 is located on one side of the device body 10 to provide access to waste material removed during the procedure, for better extraction to the outside of the body. The opening 42 is sized to allow for stable withdrawal of the harvest.

In addition, the opening 42 may be oval, right triangle, and square. The shape of the opening is not limited to ensure that the extraction can be more easily performed.

The extraction wing 44 is located at the outer edge of the opening and has a certain length, so that when the extraction object is not extracted outwards, the sealing state can be maintained, and the gas is prevented from being discharged outwards from the opening 42 at will.

Meanwhile, one end of the extraction wing 44 is opened to the outside, and the extraction object can be more easily discharged to the outside through the opening 42.

The extraction wing 44 is separately manufactured and then connected to or fixed to one side of the device body 10, or may be directly integrated with the device body 10.

The above-mentioned clip 46 is controlled on one side of the extraction wing 44 to prevent the gas from being discharged outside through the opening 42.

As shown in fig. 2, the opening 42 is provided in the device body 10 with reference to the camera port 22 in the tool insertion site 20 and with reference to the center line of the camera port 22 in the vertical direction, so that the operator can easily take the camera through the camera port 22 and confirm the extraction by the camera, and the extraction can be easily discharged from the opening 42.

In this case, the opening 42 is located in front of the camera port 22, and the lower part of the upper end of the apparatus body 10 is spaced 40 to 80 mm.

As shown in FIG. 1, more than one gas access site is provided on the device body 10, allowing for better infusion and evacuation of gas through the device body 10 for laparoscopic procedures.

In this case, the gas inlet/outlet portion 50 is divided into two portions of gas inlet and outlet, but the gas inlet and outlet may be performed simultaneously through the gas inlet/outlet portion 50.

Meanwhile, the gas inlet and outlet portion 50 may be integrally formed with the apparatus body 10, or may be separately formed and integrally installed.

The structure of the gas inlet/outlet portion 50 is the same as or similar to that of the conventional one, and detailed description thereof is omitted, and any structure or shape may be used if the structure is capable of smooth injection and exhaust.

As described above, in the state of use of the surgical glove port, see FIGS. 6a to 6f,

first, the abdominal wall fixing site 30 on the side of the insertion fixing portion 130 of the device body 10 is placed into the operation port.

In this case, as shown in fig. 6a, after the lower abdominal wall fixing part 30 of the device body 10 is mounted, as shown in fig. 6b, the lower end of the insertion fixing part 130 is opened outward, and the 1 st air bag and the 2 nd air bag of the abdominal wall fixing part 30 are placed at the upper and lower portions, respectively, so that the tool is stably set.

At this time, the 1 st and 2

nd inlet pipes

312 and 322 of the 1 st and 2

nd air bags

310 and 320 are placed at the upper outer side.

Next, as shown in fig. 6c, the 2 nd air bag 320 located at the lower portion is recessed and placed in the operation opening, and then expanded by being inflated inward by the self-elastic force of the elastic ring 324 inside the 2 nd air bag 320.

Next, as shown in FIG. 6d, the expanded 2 nd air bag 320 located inside the patient's abdominal cavity places the 1 st air bag 310 everted outside the abdominal wall.

Next, air is injected into the 1 st and 2

nd air bags

312 and 320 through the 1 st and 2

nd inlet tubes

312 and 322, and the air bags are inflated and then placed on the abdominal wall of the patient, so that the device body 10 can be stably fixed by the inflated air bags.

In addition, if the first and

second air bags

310 and 320 are used to fix the device body 10, the inflated air bags may play a role of cushioning, although the thickness of the abdominal wall varies according to the physical condition of the patient, and the abdominal wall of the patient may not be restrained or injured, and may be maintained in a fixed state.

Next, as shown in fig. 6e, after the surgical cuff 1 is provided on the abdominal wall of the patient, a surgical tool can be inserted into the upper tool insertion site 20 of the device body 10 to perform an operation.

The tool may be passed through the upper end cover plate 224 and the lip valve 222 of the tool insertion site 20 to the interior of the abdominal wall of the patient.

At this time, the tool is inserted through the access hole 2242 of the upper end cover 224, and the access hole 2242 is smaller or almost larger than the diameter of the tool to ensure that the tool rubs against the periphery of the outer rim, or to maintain the friction state of the tool against the outer rim by means of the self-elasticity of the lip valve 222, so that air is not discharged from the tool insertion portion at will even if the tool is moved.

Meanwhile, the buffering air bag 226 having the buffering band 2262 is designed inside to generate a certain buffering effect at the tool insertion site 20, thereby preventing noise and interference from being generated when the tool insertion site 20 collides and rubs with the surroundings.

Also, as shown in fig. 6f, when the waste to be extracted is generated at the affected part of the patient, it can be discharged to the outside by using the opening 42 at the side of the apparatus main body 10.

The extraction product is discharged outward by removing a clip 46 fixed to one side of the take-up wing 44 having a certain length outside the opening 42.

After the operation is completed through the above steps, the valves on the 1 st and 2 nd inlet tubes of the abdominal wall fixing part 30 may be opened to allow the gas to be discharged outside through the 1 st and 2 nd inlet tubes connected to the 1 st and 2 nd air bags.

Then, the fixing force is lost by the air fixing of the 1 st and 2 nd air bags, and the abdominal wall fixing part 30 can be easily detached from the abdominal wall part by grasping the device body 10.

The step of injecting air into the abdominal cavity is omitted from the description, and the air may be injected in a conventional manner, may be inflated or deflated inwardly through the air inlet/outlet portion 50, or may be accomplished by other means.

The sliding plate 227 is fixed by means of the mutual coupling force between the upper and lower fixing rings 228 and 229, and an inducing wing 2272 having a certain length is extended below the fixing section 212 in order to secure the fixing ability.

As shown in fig. 8, the guiding wing 2272 is designed to be inclined downward of the upper end cover 224 when being mounted on the upper end of the upper end cover 224, so that a tool can be freely inserted.

The above-mentioned induction wings 2272 are a plurality of pieces, and the plurality of pieces of induction wings 2272 are in a cut-open state and maintain a certain interval, and are located at the upper end of the upper end cover plate 224, and the plurality of pieces of induction wings 2272 are in a mutually overlapped state, preventing the upper end cover plate 224 from being involved due to mutual friction when a tool is inserted.

Meanwhile, the sliding plate 227 is made of a lighter material than the upper end cover plate 224, such as PP, PE, and the like.
