Description
Technical Field
The present disclosure relates to the field of medical devices, and more particularly to a counting device for a medical instrument and a medical instrument.
Background
The medical apparatus, in particular the use of the surgical apparatus, has a certain design service life. After the design life has expired, the use of the instrument should be prohibited or not recommended. In order to ensure that the instrument is used in the designed service life, the use condition of the instrument needs to be recorded in the use process to judge whether the instrument can be normally used. Identifying and recording instruments in the system requires that the instruments be coupled to the system and displayed by an associated display device. When the system is disconnected, the instrument can not display the recorded content, and the convenience is poor. And the instrument can not intuitively embody the specific use condition in a non-use state.
Disclosure of Invention
This section is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This section is not intended to identify essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
It is an object of the present disclosure to provide an improved counting device for medical instruments. In particular, one of the technical problems to be solved by the present disclosure is that the existing counting mechanism for medical instruments has large volume and complex structure, and does not have the functions of local self-locking and reverse rotation prevention, which can cause inconsistent indication on the instruments and in the system.
According to a first aspect of the present disclosure, a counting device for a medical instrument is provided. The counting device includes: the device comprises an upper shell, an elastic part, a suspension block with a plurality of sliding parts, a marking ring, a lower shell and a rotating part. A cavity protruding downwards is arranged at the lower part of the upper shell. The side wall of the cavity is provided with a plurality of sliding grooves extending along the up-down direction. The elastic member is stretchable in the up-down direction. The sliding parts can slide along the sliding grooves through the elastic parts between the cavity and the suspension block. A pair of first protrusions protruding downward are oppositely provided along the circumference of the levitation block at the lower portion of the levitation block.

The lower housing is assembled with the upper housing. An observation port is arranged on the side face of the lower shell. The marking of the identification ring can be observed through the observation port. The rotating member is rotatably fixed in the counting device. The identification ring can be rotated by rotating the rotating member.
According to the first aspect described above, since the indication of the information related to the counted number is achieved using the height space of the several component utilizing devices, the structure is simple and compact, the manufacturing and assembly are easy, and the related costs can be reduced. The identification ring can only rotate along the first rotation direction relative to the suspension block, so that the identification ring has a half self-locking function and can prevent counting disorder caused by rotation. In addition, a certain torsion force is needed to be provided for the rotating part in the operation process to finish the switching of the indicated information, so that recording deviation and disorder caused by the false contact can be avoided.

Detailed Description
For purposes of explanation, certain details are set forth in the following description in order to provide a thorough understanding of the disclosed embodiments. It is apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details or with an equivalent arrangement.
The available space in the surgical instrument is smaller, but most of the existing modes for recording the using times of the instrument by using the instrument body have the problems of larger volume and complex structure, so the cost is relatively higher and the assembly difficulty is certain. Moreover, the automatic control device does not have the functions of local self-locking and reverse rotation prevention, so that the recording mechanism is touched by mistake with a certain probability under the conditions of storage, transportation, cleaning, disinfection and the like, and the phenomenon that the indication on the instrument is inconsistent with the system is caused, so that the recording is deviated.
The present disclosure provides an improved counting device for medical instruments and medical instruments. Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of a surgical instrument in which the principles of the present disclosure may be applied. As shown in fig. 1, the surgical instrument includes an instrument pod 12, an instrument bar 14, and an instrument tip 16. A counting device according to an embodiment of the present disclosure, which will be described later, may form part of the instrument cartridge 12 for counting the number of uses of the surgical instrument. The instrument tip 16 may be a forceps, a curved scissors, or the like.
Fig. 2 is a schematic diagram of a system in which the principles of the present disclosure may be applied. As shown in fig. 2, the system 20 is a mobile surgical platform that is a component of a surgical robot. The movable surgical platform has an instrument drive cassette 21. The instrument cassette 12 of the surgical instrument shown in fig. 1 may be mounted to an instrument drive cassette 21. The instrument drive cassette 21 may drive the instrument shaft 14 and instrument tip 16 (e.g., jaws) of a surgical instrument for performing a surgical procedure. For example, when it is determined that the surgical instrument has been used once according to a predetermined criterion, the movable surgical platform 20 may control the instrument drive cassette 21 to operate the counting device included in the instrument cassette 12 so as to increment the count value of the counting device by one.
Next, a counting device of the present disclosure, which may constitute a part of an instrument cassette of a surgical instrument, will be described as an example. However, those skilled in the art will appreciate that the principles of the present disclosure may also be applied to other medical devices having a limited number of uses. Fig. 3 is an exploded view of a surgical instrument cassette according to an embodiment of the present disclosure. As shown in fig. 3, the surgical instrument cassette 30 includes: the upper case 31, the elastic member 32, the suspension block 33 having the plurality of sliding portions 331, the identification ring 34, the lower case 35, and the rotating member 36. A cavity 311 protruding downward is provided at a lower portion of the upper housing 31. The side wall of the cavity 311 has a plurality of sliding grooves 312 extending in the up-down direction. Although the number of the sliding grooves 312 is 2 in the example shown in fig. 3, the number of the sliding grooves 312 may be more than 2. The elastic member 32 is stretchable in the up-down direction. Although a spring is employed as the elastic member 32 in the example of fig. 3, any other suitable elastic member may be employed. The sliding portions 331 can slide along the sliding grooves 312 by the elastic member 32 located between the cavity 311 and the suspension block 33. The number of sliding portions 331 may be equal to the number of sliding grooves 312. Although the number of the sliding parts 331 is 2 in the example shown in fig. 3, the number of the sliding parts 331 may be more than 2. Fig. 5A more clearly shows the state of the upper case 31, the elastic member 32, and the levitation block 33 before assembly. Fig. 5B shows a state in which the upper case 31, the elastic member 32, and the levitation block 33 are assembled together.
Referring back to fig. 3, a pair of first protrusions 332 protruding downward are oppositely provided along the periphery of the levitation block 33 at the lower portion of the levitation block 33. Since the pair of first protrusions 332 are disposed opposite to each other, when the tag ring 34 described later is rotated with respect to the levitation block 33, the levitation block 33 can receive an equalized upward thrust force via the pair of first protrusions 332. It should be noted that one or more pairs of first protrusions may be optionally additionally provided along the periphery of the suspending block 33 at the lower portion of the suspending block 33, as long as all the first protrusions are provided at uniform intervals along the periphery of the suspending block 33 and can be mutually engaged with the second protrusions 341 of the later-described identification ring 34 to complete counting.
A plurality of second protrusions 341 protruding upward from each other and spaced apart are provided at an upper portion of the identification ring 34. The pair of first protrusions 332 and the plurality of second protrusions 341 are configured such that the identification ring 34 is rotatable with respect to the levitation block 33 only in the first rotational direction. As one example, fig. 8 illustrates the relative movement between the marker ring and the levitation block. In the example of fig. 8, a later-described marking provided on the side of the identification ring directly indicates the number of counts, a pattern which may also be referred to herein as a count pattern. As shown in fig. 8, each first protrusion 332 may have: a first inclined sliding surface 3321; a first horizontal sliding surface 3322 connected to the first inclined sliding surface 3321; and a first vertical stop surface 3323 connected to the first horizontal slide surface 3322. Each of the second protruding portions 341 may have: a second inclined sliding surface 3411; a second horizontal sliding surface 3412 connected to the second inclined sliding surface 3411; and a second vertical stop surface 3413 connected to the second horizontal slide surface 3412. In fig. 8, when the tag ring 34 rotates counterclockwise with respect to the floating block 33, the second inclined sliding surface 3411 of the second protrusion 341 first slides against the first inclined sliding surface 3321 of the first protrusion 332, so that the floating block 33 is pushed upward of the tag ring 34. Then, the second horizontal sliding surface 3412 of the second protruding portion 341 slides against the first horizontal sliding surface 3322 of the first protruding portion 332. Next, the first protrusions 332 fall into the spaces (or grooves) between the second protrusions 341 such that the first vertical stop surfaces 3323 of the first protrusions 332 contact the second vertical stop surfaces 3413 of the second protrusions 341. Since the two vertical stop surfaces block each other, the identification ring 34 cannot rotate in a clockwise direction with respect to the levitation 33, but only in a counter-clockwise direction.
As another example, fig. 7A/7B illustrates the relative movement between the identification ring and the levitation block. In the example of fig. 7A/7B, a later-described flag provided on the side of the identification ring indicates a status ("Y" indicates available, "N" indicates unavailable) corresponding to the counted number as to whether the surgical instrument is available, which may also be referred to herein as a status indication mode. That is, the identification ring indicates only two results, such as normal number of instrument uses ("Y") and spent number of instrument uses ("N"), and does not represent an intermediate number, only serves as a status indication. As shown in fig. 7A, each second protrusion 341 may have: a second inclined sliding surface 3411; a second horizontal sliding surface 3412 connected to the second inclined sliding surface 3411; and a second vertical stop surface 3413 connected to the second horizontal slide surface 3412. Note that in fig. 7A, in the case where a locking mechanism described later is not provided, the first protrusion 332 may have only the first inclined sliding surface 3321, the first horizontal sliding surface 3322, and the first vertical stopper surface 3323 as shown in fig. 8. Accordingly, the relative rotation between the identification ring and the levitation may also be similar to fig. 8.
It should be noted that the present disclosure is not limited to the examples described above. The first projection 332 and the second projection 341 may also have other suitable configurations, as long as the identification ring 34 can only rotate in the first rotational direction with respect to the levitation block 33. For example, the second protruding portion 341 may remain the same as that shown in fig. 8, and the first protruding portion 332 may have a first vertical locking surface 3324 (described later), a first inclined sliding surface 3321, a first horizontal sliding surface 3322, and a first vertical stopper surface 3323 as shown in fig. 7A. This configuration can obtain the same effect as the configuration of fig. 8.
Referring back to fig. 3, indicia 342 are provided on the side of the identification ring 34 for indicating information about the number of second protrusions 341 spanned by the first protrusions 332 due to rotation of the identification ring 34. In the example of fig. 3, the indicated information is a usage status corresponding to the number as to whether the surgical instrument can be used further (as previously described, "Y" indicates available, "N" indicates unavailable). As another example, the indicated information may be the number of second protrusions that the first protrusions cross due to rotation of the identification ring, as shown in fig. 8.
As shown in fig. 3, the lower case 35 is assembled with the upper case 31. A viewing port 351 is provided on a side surface of the lower case 35. The indicia 342 of the identification loop 34 can be viewed through the viewing port 351. The rotary member 36 is rotatably fixed in the surgical instrument cassette 30. The identification ring 34 can be rotated by rotating the rotating member 36. In the example of fig. 3, the rotating member 36 is a rotating shaft that is rotatably fixed in the upper housing 31 by a snap spring 37 through the lower housing 35, the identification ring 34, the suspension block 33, the elastic member 32, the cavity 311, as shown in fig. 4 (which is a sectional view of the surgical instrument cassette according to this embodiment). Fig. 6A and 6B more clearly show a state in which the rotation shaft, the lower housing, and the identification ring are assembled together. As shown in fig. 6A/6B, the identification ring 34 may be fitted over the rotation shaft 36 after the rotation shaft 36 passes through the lower housing 35. The upper part of the rotating shaft 36 has a shaped structure corresponding to the hole of the identification ring 34, so that the rotating shaft 36 can drive the identification ring 34 to rotate synchronously when rotating. It should be noted that the present disclosure is not limited to this example. The rotary member 36 may have any other suitable structure as long as it is rotatably secured in the surgical cassette 30 and rotates the identification ring 34.
With the surgical instrument cassette 30 described above, since the indication of the information related to the counted number is achieved using several components using the height space of the device, the structure is simple and compact, the manufacturing and assembly are easy, and the related costs can be reduced. The identification ring can only rotate along the first rotation direction relative to the suspension block, so that the identification ring has a half self-locking function and can prevent counting disorder caused by rotation. In addition, a certain torsion force is needed to be provided for the rotating part in the operation process to finish the switching of the indicated information, so that recording deviation and disorder caused by the false contact can be avoided. Further, since the information on the number of times of use of the medical device can be seen through the observation port, whether the medical device can be used can be intuitively judged.
Optionally, a locking mechanism may be provided on the levitation 33 and the identification ring 34 for preventing rotation of the identification ring 34 relative to the levitation 33 when the first protrusion 332 crosses a predetermined number (e.g., the maximum number of counts available for the identification ring) of the second protrusions 341 due to rotation of the identification ring 34. As an example, as shown in fig. 7A/7B, the lock mechanism includes: a first vertical locking surface 3324 provided on one of the pair of first protrusions 332, opposite to the first vertical stop surface 3323, and connected to the first inclined sliding surface 3321; and a second vertical locking surface 3414 provided on one of the second protruding portions 341 between the second inclined sliding surface 3411 and the second horizontal sliding surface 3412. Thus, as shown in fig. 7A, when the first vertical locking surface 3324 of the first protrusion 332 contacts the second vertical locking surface 3414 of the second protrusion 341, the two vertical locking surfaces block each other, so that the tag ring 34 cannot continue to rotate in the counterclockwise direction with respect to the suspending block 33. As previously described, the identification ring 34 cannot rotate in a clockwise direction relative to the levitation 33 because the first vertical stop surface 3323 of the first protrusion 332 and the second vertical stop surface 3413 of the second protrusion 341 block each other. In this way, the surgical instrument cassette has a full self-locking function, so that when the surgical instrument cassette is switched to a status indication or last digit, for example, corresponding to the maximum count number of identification rings, the surgical instrument cassette can be fully automatically locked, indicating that the corresponding surgical instrument cannot be used any more. It should be noted that depending on the particular application, the other first protrusion 332 of the pair of first protrusions 332 may or may not have the first vertical locking surface 3324.
In the configuration shown in fig. 7A and 7B, the first protrusions of the suspension block may be located in the spaces (or grooves) between the second protrusions on the identification ring during normal use, with the indicia "Y" on the side of the identification ring aligned with the viewing port. When the last use of the surgical instrument is detected (e.g., by the surgical platform of the surgical robot), the identification ring is rotated in the direction of the arrow. Under the action of the second sliding surface of the second protrusion, the suspension block is lifted up by the upward force, as shown in fig. 7B. When the suspension block rotates to the next slot position, the marks 'N' on the side surfaces of the identification ring are aligned with the observation ports, and at the moment, the vertical surfaces on the two sides of the first protruding part of the suspension block are matched with the vertical surfaces of the corresponding grooves on the identification ring, so that the suspension block enters a locking state, as shown in fig. 7A.
As another example, as shown in fig. 9A and 9B, the locking mechanism may include: a locking recess 333 provided at the bottom of one first protrusion 332 of the pair of first protrusions 332; and a locking protrusion 343 matching the locking recess 333 provided at one of the plurality of intervals between the plurality of second protrusions 341. Further, a escape recess 334 for escaping the locking protrusion 343 is provided at the bottom of the other first protrusion 332 of the pair of first protrusions 332, so that the tag ring 34 can be further rotated with respect to the suspending block 33 when the locking protrusion 343 enters the escape recess 334 of the other first protrusion 332.
Fig. 10 is a schematic view showing an initial count state of the surgical instrument cassette having the locking mechanism shown in fig. 9A and 9B. As shown in fig. 10, in the initial counting state, the first protrusion 332 provided with the locking recess is offset from the locking protrusion 343 on the identification ring, and the mark "0" on the side of the identification ring is aligned with the viewing port on the lower housing.
Fig. 11A and 11B are schematic views showing an intermediate count state of the surgical instrument cassette having the locking mechanism shown in fig. 9A and 9B. In this intermediate counting state, the locking protrusion 343 is rotated in the counterclockwise direction to the position shown in fig. 11B, and the mark "3" on the side of the identification ring is aligned with the viewing port on the lower housing. Since the locking protrusion 343 falls into the escape recess, the identification ring can continue to rotate in a counter-clockwise direction relative to the suspension block.
Fig. 12A and 12B are schematic views showing a final lock state of the surgical instrument cassette having the lock mechanism shown in fig. 9A and 9B. In this final locking state, the locking protrusion 343 is rotated one turn in the counterclockwise direction to come into contact with the first protrusion 332 provided with the locking recess. Since the locking protrusion is matched with the locking recess, the identification ring cannot continue to rotate in the counterclockwise direction. As mentioned before, the identification ring cannot be rotated in a clockwise direction due to the vertical stop surfaces of the two protrusions blocking each other. In this way, the surgical instrument cassette can also have a full self-locking function, so that when the surgical instrument cassette is switched to a status indication or last digit, for example, corresponding to the maximum count number of identification rings, the surgical instrument cassette can be fully automatically locked, indicating that the corresponding surgical instrument cannot be used any more.
In the configurations shown in fig. 10, 11A and 11B, and 12A and 12B, corresponding slots are added to the identification ring on the basis of the status indication effect, as compared with the configurations shown in fig. 7A and 7B. The initial point is 0, and the final locking point corresponds to the maximum use times of the instrument. During normal times display, the rotating shaft drives the identification ring to rotate in the direction shown in fig. 11B, and the suspension block can be lifted upwards under the extrusion of the second sliding surface of the second protruding part. When moving to the next slot, the first protrusion on the floating block will drop, switching to the next number. The identification ring is provided with a locking protrusion, one of two recesses arranged on two opposite first protruding parts of the suspension block plays a role in limiting locking when the suspension block runs for the maximum times, and the other recess plays a role in avoiding so as to facilitate normal digital switching. When the maximum use times are counted, the locking protrusions on the identification ring can fall into the locking depressions of the corresponding first protruding portions on the suspension block, so that the identification ring and the suspension block cannot relatively displace, and self-locking is completed, as shown in fig. 12B.
Fig. 13 is a perspective view of a surgical instrument cassette according to an embodiment of the present disclosure. By rotating the rotating member 36 in the direction of the arrow shown in fig. 13, the number of uses of the surgical instrument can be counted. The counted number of uses can be visually seen through the viewing port 351. In the example of fig. 13, the surgical instrument cassette has an instrument bar 14 mounted thereon. For example, in the case where the instrument end attached to the instrument bar 14 is a pair of pliers, the rotating members 131 and 132 at the bottom of the instrument cartridge are used to control opening and closing of the jaws, the rotating member 133 is used to control deflection of the jaws, and the rotating member 134 is used to control rotation of the instrument bar. When connected with the instrument driving box 21 in fig. 2, the instrument driving box can drive the rotating parts 131-134 in the instrument box to rotate, so that the surgical instrument works. At the same time, the instrument drive cartridge may drive the rotary member 36 in the direction of the arrow shown in the figures, thereby bringing the identification ring to count or status indication. Although the surgical instrument cassette has an instrument bar mounted thereon in the example of fig. 13, it should be noted that the surgical instrument cassette sold as a product may not contain an instrument bar. In addition, the rotating members 131 to 134 may be configured and arranged in the conventional manner, and the present disclosure is not particularly limited in this respect.
