Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and more particularly to a minimally invasive surgical pad for tendon and ligament avulsion fractures. Background Art

[0002] Surgical pads are a type of medical device that is widely used in surgical operations or rehabilitation treatments.

[0003] In the prior art patent CN203634290U, the surgical pad includes a rectangular positioning pad body, on which an arc-shaped groove running through the positioning pad body is provided, and the length of the arc-shaped groove is the same as the length of the positioning pad body, and the cross-sectional shape of the positioning pad body is U-shaped, soft leather is laid on the outside of the positioning pad body, and polymer sponge is filled inside the positioning pad body. It can be seen that the patent CN203634290U is limited by the penetrating structure of the arc-shaped groove, but due to the unilateral constraint of the arc-shaped groove, it cannot be contracted and clamped on both sides, and the clamping constraint of the penetrating object cannot be achieved.

[0004] Therefore, how to provide a minimally invasive surgical pad for tendon and ligament avulsion fractures that can clamp and constrain penetrating objects through cavity contraction is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] In view of this, the present invention provides a minimally invasive surgical pad for tendon and ligament avulsion fractures, which aims to solve the above-mentioned deficiencies.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A minimally invasive surgical pad for tendon and ligament avulsion fractures, used to constrain sutures, comprises: an arcuate pressure plate and a base; the downwardly curved end of the arcuate pressure plate is connected to the top surface of the base; a cavity is left between the upwardly protruding end of the arcuate pressure plate and the base; the suture passes through the cavity.

[0008] Preferably, the top surface of the arc-shaped pressure plate protrusion is provided with anti-slip grooves.

[0009] Preferably, a bubble level is provided on the side wall of the base.

[0010] Preferably, the arc-shaped pressing plate and the base are integrally formed.

[0011] Preferably, the arc-shaped pressing plate and the base are both made of PEEK material.

[0012] Compared with the prior art, the utility model has achieved the following technical effects:

[0013] 1. The minimally invasive surgical pad includes: a curved pressure plate and a base. During use, the suture passes through the cavity, and the curved pressure plate is squeezed downward from the top end to reduce the volume of the cavity, so that the curved pressure plate and the base are squeezed and matched to constrain the suture, ultimately achieving clamping and constraining of the penetrating object through cavity contraction;

[0014] 2. The top surface of the arc-shaped pressing plate is provided with anti-slip grooves to prevent the top of the arc-shaped pressing plate from slipping when pressed by hand;

[0015] 3. The horizontal position of the base can be calibrated by the bubble level.

[0016] In summary, the overall structure of the present invention is compact and reasonably arranged. By reducing the volume of the cavity, the arc-shaped pressure plate and the base are squeezed and fitted to constrain the suture, and ultimately the penetrating object is clamped and constrained by the contraction of the cavity.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example

[0022] Reference Figure 1 The minimally invasive surgical pad shown is for tendon and ligament avulsion fractures, and is used to constrain sutures 1. The minimally invasive surgical pad includes: an arc-shaped pressure plate 2 and a base 3, wherein the downwardly bent end of the arc-shaped pressure plate 2 is connected to the top surface of the base 3, and a cavity is left between the upwardly protruding end of the arc-shaped pressure plate 2 and the base 3 for the suture 1 to pass through.

[0023] The raised top surface of the arc-shaped pressing plate 2 is provided with anti-skid grooves to prevent the hand from slipping during squeezing.

[0024] A bubble level 4 is provided on the side wall of the base 3 to facilitate calibration of the horizontal position of the entire structure.

[0025] The arc-shaped pressing plate 2 and the base 3 are integrally formed to improve the stability of the overall structure.

[0026] In this embodiment, the arc-shaped pressing plate 2 and the base 3 are both made of PEEK.

[0027] In this embodiment, the minimally invasive surgery pad is 8 mm in length, 4 mm in width, and 3 mm in height.

[0028] Working process:

[0029] During the operation, the suture 1 passes through the cavity. When the suture does not need to be fed, the curved pressing plate 2 is pressed with fingers to squeeze the suture 1, thereby restricting the movement of the suture 1 and preventing the suture 1 from cutting the bone tissue.

[0030] Among them, the anti-slip grooves prevent the fingers from moving and deviating, and the bubble level 4 prevents the minimally invasive surgery pad from tilting;

[0031] When the thread needs to be fed, the fingers leave the arc-shaped pressing plate 2 to open the cavity, and the suture 1 moves freely.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
