Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a single-handed operation clamping tool for the process of strabismus surgery. Background Art

[0002] In existing strabismus correction surgeries, usually two-person operation is required: one person uses a surgical hook to separate the eye muscle from the iris, and the other person performs the suturing operation. Since the surgical space in the eye is extremely limited (usually only about 8mm×8mm), two-person operation not only increases the surgical difficulty, but also may lead to the risk of insufficient muscle stripping or muscle breakage. In addition, during the suturing process, the operating space of the suture needle is greatly affected by the manual lifting. If the lifting is too small, it may damage the iris and affect the surgical effect.

[0003] Therefore, there is an urgent need for a special tool that can clamp, traction, and fix the eye muscle through single-handed operation to improve the accuracy and safety of the surgery. Summary of the Invention

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that existing strabismus correction surgeries usually require two-person operation, so the tools required for current strabismus correction surgeries are not suitable for single-person use, which increases the surgical difficulty, leads to the risk of insufficient muscle stripping or muscle breakage, and the surgical effect is not good, etc. Therefore, the present invention provides a single-handed operation clamping tool for the process of strabismus surgery, which can open up the surgical space, clamp and limit, and traction and fix the eye muscle with one hand to solve the problems of narrow operation space, high operation difficulty, and high surgical risk in the prior art.

[0005] To achieve the above object, the present invention provides a single-handed operation clamping tool for the process of strabismus surgery, which has an elastic clamping part and an operation space with a cross design. When in use, the elastic clamping part is operated with one hand to separate the operation space, so as to realize the clamping, traction, and fixation of the eye muscle; specifically,

[0006] It includes a clamping upper plate and a clamping lower plate. The clamping upper plate and the clamping lower plate are fixedly connected. The clamping upper plate includes a first elastic hand-held part and a first operation space. The clamping lower plate includes a second elastic hand-held part and a second operation space. One end of the first elastic hand-held part is fixedly connected to one end of the second elastic hand-held part. The other end of the first elastic hand-held part is connected to the first operation space. The other end of the second elastic hand-held part is connected to the second operation space. The clamping upper plate and the clamping lower plate are designed to cross each other in space.

[0007] Furthermore, the first operation space for clamping the upper plate includes a first connecting member, a muscle support platform, a needle insertion operation space, and a muscle peeling and expanding member. The muscle support platform is connected to the first elastic handheld portion through the first connecting member, and the other end of the muscle support platform is connected to the muscle peeling and expanding member. Among them, the muscle support platform includes a first muscle support platform and a second muscle support platform, and the needle insertion operation space is arranged between the first muscle support platform and the second muscle support platform.

[0008] Furthermore, one end of the first muscle support platform is connected to the first connecting member, and the other end is connected to the muscle peeling and expanding member; one end of the second support platform is designed to be suspended, and the other end is connected to the muscle peeling and expanding member.

[0009] Furthermore, the first connecting member is set as a first connecting member with an included angle, and the included angle between the first connecting member and the first elastic handheld portion is 140° - 150°.

[0010] Furthermore, the width of the first connecting member is less than half of the width of the elastic handheld portion, and the edge of one side of the first connecting member is flush with the edge of the first elastic handheld portion.

[0011] Furthermore, the muscle support platform is set as a serrated joint surface.

[0012] Furthermore, the pitch of the serrated joint surface is 0.3 - 0.5 mm, the depth is 0.1 mm, and there are no sharp edges.

[0013] Furthermore, the second operation space for clamping the lower plate includes a second connecting member, a muscle clamping portion, and a traction hole. The muscle clamping portion is connected to the second elastic handheld portion through the second connecting member, and the traction hole is arranged on the platform of the muscle clamping portion.

[0014] Furthermore, the platform of the muscle clamping portion is provided with a serrated joint surface, the pitch is 0.3 - 0.5 mm, the depth is 0.1 mm, and there are no sharp edges.

[0015] Furthermore, the traction holes are set to be 2, and are respectively arranged at both ends of the serrated joint surface.

[0016] Technical effects

[0017] A single - hand operation clamping tool for strabismus surgery provided by the present invention can complete the clamping, traction, and fixation of the eye muscles through single - hand operation, greatly releasing the surgical operation space and making single - person surgical operation possible.

[0018] The progressive muscle peeling and expanding part of the clamping tool standardizes the muscle peeling distance, avoiding the risks of insufficient peeling or excessive peeling.

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] In the following description, specific details such as specific internal programs and technologies are proposed for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. However, those skilled in the art should clearly understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, the detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details from interfering with the description of the present invention.

[0025] As Figures 1-3 shown, the present invention provides a single-handed operation clamping tool for strabismus surgery, which has an elastic clamping part and an operation space with a cross design. When in use, the elastic clamping part is operated with one hand, so that the operation space is separated, realizing the clamping, traction and fixation of the eye muscles; specifically,

[0026] It includes a clamping upper plate 1 and a clamping lower plate 2 which are fixedly connected. The clamping upper plate 1 includes a first elastic hand-held part 1.1 and a first operation space, and the clamping lower plate 2 includes a second elastic hand-held part 2.1 and a second operation space. One end of the first elastic hand-held part 1.1 is fixedly connected to one end of the second elastic hand-held part 2.1, the other end of the first elastic hand-held part 1.1 is connected to the first operation space, and the other end of the second elastic hand-held part 2.1 is connected to the second operation space. The clamping upper plate 1 and the clamping lower plate 2 are designed to cross each other in space. This cross design enables a doctor, when using it during a surgical operation, to pinch the elastic hand-held parts with one hand, separating the first operation space and the second operation space, which facilitates the doctor to perform the surgery. The invention provides a single-handed operation clamping tool for the process of strabismus surgery, which is made of 316L medical stainless steel or titanium alloy material.

[0027] The first operation space of the clamping upper plate 1 includes a first connecting piece, a muscle support platform 1.2, a needle insertion operation space 1.3 and a muscle peeling and expanding component 1.4. The muscle support platform 1.2 is connected to the first elastic hand-held part through the first connecting piece, and the other end of the muscle support platform 1.2 is connected to the muscle peeling and expanding component 1.4; among them, the muscle support platform 1.2 includes a first muscle support platform and a second muscle support platform, and the needle insertion operation space 1.3 is arranged between the first muscle support platform and the second muscle support platform. The muscle peeling and expanding component 1.4 adopts a progressive method to gradually peel the muscle to a fixed size, making the space operation more consistent, avoiding the problem of inconsistent width caused by manual peeling, such as peeling too large or too small. In this embodiment, the peeling width of the muscle peeling and expanding component is set to 5 - 6 mm. The head (the end far from the first elastic hand-held part) of the muscle peeling and expanding component 1.4 is rounded, the maximum width of the head is set to 2 - 3 mm, and the maximum width of the muscle peeling and expanding component 1.4 is 5 - 6 mm. From the head to the widest part of the muscle peeling and expanding component 1.4, its width increases progressively, and its edge is a straight line. The design of the muscle peeling and expanding component 1.4 avoids damaging the muscle and makes it easier for the muscle peeling and expanding component to enter the lower side of the muscle, facilitating the operation.

[0028] In addition, one end of the first muscle support platform is connected to the first connecting piece, and the other end is connected to the muscle peeling and expanding component; one end of the second support platform is designed to be suspended, and the other end is connected to the muscle peeling and expanding component.

[0029] The first connecting piece is set as a first connecting piece with an included angle, and the included angle between the first connecting piece and the first elastic hand-held part is 140° - 150°. After heat treatment, the clamping upper plate and the clamping lower plate have elasticity. The design of the included angle enables the end of the clamping plate to generate displacement when pressed. With an appropriate angle design, the pressing force is appropriate, and the height difference generated when stressed is within 15 - 20 mm.

[0030] The width of the first connecting member is less than half of the width of the first elastic grip portion, and the edge of one side of the first connecting member is flush with the edge of the first elastic grip portion. Correspondingly, the width of the second connecting member is less than half of the width of the second elastic grip portion, and the edge of one side of the second connecting member is flush with the edge of the second elastic grip portion, and the corresponding edges of the first connecting member and the second connecting member are opposite sides, so that after pinching the first elastic grip portion and the second elastic grip portion, the first operating space and the second operating space have a more precise movable space.

[0031] The muscle support platform is set as a serrated joint surface. The pitch of the serrated joint surface is 0.3-0.5mm, the depth is 0.1mm, and there is no sharp edge. The serrated joint surface design increases the clamping friction, prevents muscle slippage, and ensures surgical safety.

[0032] The second operating space of the clamping lower plate 2 includes a second connecting piece, a muscle clamping part 2.2 and a traction hole 2.3. The muscle clamping part 2.2 is connected to the second elastic hand-held part 2.1 through the second connecting piece, and the traction hole 2.3 is set on the platform of the muscle clamping part. The platform of the muscle clamping part is provided with a serrated joint surface with a pitch of 0.3-0.5mm, a depth of 0.1mm, and no sharp edges. The serrated joint surface design increases the clamping friction, prevents muscle slippage, and ensures surgical safety.

[0033] There are two traction holes, which are respectively arranged at the two ends of the serrated joint surface. The traction holes can adjust the surgical space to the optimal position through the traction rope to facilitate subsequent suturing operations.

[0034] The included angle between the second elastic handle and the second connecting member is set to 140°-150°.

[0035] The present invention is a one-handed clamping tool for strabismus surgery, wherein the static total height of the clamping upper plate 1 and the clamping lower plate 2 does not exceed 5 mm, the width does not exceed 10 mm, and the total length is 50-60 mm. The space structure is small, which can release more operating space. In this embodiment, when the clamping upper plate and the clamping lower plate are pressed hard, the height difference between the clamping upper plate and the clamping lower plate is 15-20 mm.

[0036] The height difference between the muscle clamping part clamping the lower plate and the muscle spreading and expanding part clamping the upper plate is 3-4mm, which can ensure that the stretching of the eye muscles is precisely controlled and can reduce the stretching of the muscles as much as possible while ensuring the operating space for the eye muscles with different elasticities.

[0037] The head of the muscle stripping and expansion part of the clamping upper plate must be rounded, with a head width of 2-3mm. The eye corners can avoid damage to the muscles, and the 2-3mm width makes it easier for the lower plate to enter the lower side of the muscle until the muscle contacts the muscle clamping part, making operation easier.

[0038] The following will use a specific embodiment to illustrate the one-handed clamping tool used in strabismus surgery of the present invention to achieve the functions of surgical space development, clamping and limiting, and traction and fixation of eye muscles with one hand. The above functions are divided into three steps.

[0039] The first step is the process of expanding the eye muscle and iris space. Specifically, when the operation reaches the stage where the surgical hook is used to initially separate the muscle and iris, the clamping tool can be used. The parts involved in the work at this stage are mainly the first elastic hand-held part 1.1 for clamping the upper plate 1, the muscle peeling and expansion part 1.4, and the second elastic hand-held part 2.1 for clamping the lower plate 2. Specifically, the operating doctor can use the thumb and index finger to press the first elastic hand-held part 1.1 for clamping the upper plate 1 and the second elastic hand-held part 2.1 for clamping the lower plate 2 to separate the muscle supporting platform 1.2 of the clamping upper plate 1 and the muscle clamping part 2.2 of the clamping lower plate 2, and extend the muscle peeling and expansion part 1.4 of the clamping upper plate 1 into the lower side of the muscle. The muscle peeling and expansion part 1.4 is a shape that expands in width from small to large, which can effectively peel the muscle and iris.

[0040] The second step is the clamping process. Specifically, after the eyeball muscles and iris are effectively separated after the operation in the previous step, the tool is further inserted so that the eye muscles completely fall on the muscle support platform 1.2 of the clamping upper plate 1. At this time, the doctor can loosen the thumb and index finger to remove the force on the first elastic hand-held part 1.1 of the clamping upper plate 1 and the second elastic hand-held part 2.1 of the clamping lower plate 2, so that the eye muscles fall between the muscle support platform 1.2 of the clamping upper plate 1 and the muscle clamping part 2.2 of the clamping lower plate 2, and the eye muscles are fixed. The muscle support platform 1.2 of the clamping upper plate 1 and the muscle clamping part 2.2 of the clamping lower plate 2 have a serrated joint surface with a tooth pitch of 0.3-0.5mm and a depth of 0.1mm. This structure can effectively increase the friction between the muscle and the clamping tool, making the clamping safer and more reliable, and avoiding the possibility of relative sliding after clamping. Among them, the muscle clamping part plays a role in fixing the muscles to cooperate with subsequent traction and to fix the surgical position when operated by one person; the needle insertion operation space is the needle insertion position during suture operation to avoid tools blocking the operation window and interfering with the surgical needle insertion operation.

[0041] The third step is the traction fixation process. Specifically, before the operation, a traction rope is tied in advance on the traction hole 2.3 of the clamping lower plate 2. After the second step of operation is completed, according to the requirements of the subsequent operation space, the traction rope is traction-fixed in the relevant direction so that the surgical position is in a convenient and easy-to-operate space. After the traction rope is effectively fixed, the subsequent suture operation can be carried out using the needle insertion operation space 1.3 of the clamping upper plate 1. After the operation is completed, the operating doctor can press the elastic hand-held parts 1.1 of the clamping upper plate 1 and the elastic hand-held parts 2.1 of the clamping lower plate 2 with the thumb and index finger to separate the muscle support platform 1.2 of the clamping upper plate 1 and the muscle clamping part 2.2 of the clamping lower plate 2, and withdraw the clamping tool from the eye muscle.

[0042] As can be seen from the description, the above three-step operations can all be carried out orderly by a single person.

[0043] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
