Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, in particular to a fixing device for suturing a shoulder joint. Background Art

[0002] A suture needle is a medical device used to penetrate tissue and fix sutures during surgery or wound suturing. Suture needles are usually made of metal or plastic, with a sharp needle tip and a needle body suitable for puncturing tissue. In shoulder joint surgery, medical staff usually use specially designed suture needles to suture tissue and skin.

[0003] For example, the utility model with the publication number CN210056154U provides a surgical tweezers to solve the problem of poor hand-holding feel of existing tweezers. The surgical tweezers are composed of a pressing part, an opening and closing part, a closing part, an elastic component and a transmission pin, wherein the upper section of the elastic component is a parabolic curve design, the lower section is a semicircular transition, and the lower end of the elastic component and the pressing part are pressure welded along the tangent direction. A 90-degree swivel is provided at one end of the pressing part close to the welding point; the rotating pin is a friction-resistant alloy pin shaft, which is overfitted with the pin hole at the opening and closing part. After the overall performance is optimized, the utility model improves the comfort of hand-holding, facilitates precise surgery, and relieves finger fatigue, especially during long-term surgery. The hand-held part has high rigidity, which improves the accuracy of clamping and avoids large bending in the hand-held part.

[0004] When the above device is in use, the special elastic component design enhances the comfort of the medical staff in holding the tweezers. However, when the device clamps the suture needle, the surface of the suture needle is curved, which leads to a decrease in the contact area between the tweezers and the suture needle, thereby reducing the stability and friction of the grasping, and further causing the suture needle to slip when passing through human tissue, affecting the accuracy and efficiency of the surgical operation. Therefore, a fixation device for shoulder joint suturing is proposed to address the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5As shown, the utility model provides a fixing device for shoulder joint suturing, comprising a clamp housing 1, a pinhole 2 is fixedly connected to the bottom end of the clamp housing 1, an arc block 3 is movably connected to the inner ring of the pinhole 2 at equal angles, gaskets 4 are fixedly connected to the opposite sides of the two arc blocks 3, a limiting rod 5 is fixedly connected to the other side of the arc block 3, an oblique block 6 is fixedly connected to the top of the limiting rod 5, a first connecting rod 7 is movably connected to the inside of the clamp housing 1, a second connecting rod 8 is hinged to the top of the first connecting rod 7, a third connecting rod 9 is hinged to the end of the second connecting rod 8 away from the first connecting rod 7, pressure blocks 10 are fixedly connected to the opposite ends of the two third connecting rods 9, a spring rod 11 located on both sides of the first connecting rod 7 is fixedly connected to the inside of the clamp housing 1, and a spring piece 12 is fixedly connected between the two oblique blocks 6.

[0023] By pressing the pressure block 10, the two third connecting rods 9 are driven to move toward each other, thereby driving the first connecting rod 7 downward through the second connecting rod 8, and then the first connecting rod 7 squeezes the inclined block 6 and makes the two inclined blocks 6 move toward each other. When the inclined block 6 moves, it drives the limiting rod 5 to move in the same direction, so that the two arc blocks 3 at the lower end of the limiting rod 5 drive the gasket 4 to move toward each other and clamp the suture needle inside the needle hole 2 to keep it stable.

[0024] like Figures 1 to 5 As shown, the gasket 4 is made of silicone material, and the opposite sides of the two gaskets 4 are tooth-shaped, the limiting rod 5 is L-shaped, and the bottom end of the limiting rod 5 passes through the outer wall of the clamp housing 1 and the pinhole 2, and extends to the inside of the pinhole 2. The bottom end of the first connecting rod 7 is inclined, and the top of the opposite side of the inclined block 6 is inclined, and the inclined surfaces of the two are abutted, and the opposite ends of the two third connecting rods 9 pass through the outer wall of the clamp housing 1 and extend to the outside of the clamp housing 1, and the clamp housing 1 is scissors-shaped.

[0025] The gasket 4 is made of silicone material, and its function is that since the silicone material has good high temperature resistance, it can maintain stability during high temperature disinfection. At the same time, the silicone material has good corrosion resistance to common disinfectants and medicines. One side of the gasket 4 is serrated, and its function is that the serrated design can provide better gripping force and stability, thereby helping medical staff to operate the suture needle more accurately during surgery, thereby improving surgical efficiency and accuracy. The clamp housing 1 is scissors-shaped, and its function is to ensure that the handle part of the clamp housing 1 conforms to the ergonomic principle of human hand holding, thereby providing a comfortable grip and stability, thereby facilitating medical staff to use it for a long time.

[0026] like Figures 1 to 5As shown, when the two third connecting rods 9 move toward each other, the first connecting rod 7 is driven downward by the second connecting rod 8. When the first connecting rod 7 moves downward, it squeezes the inclined block 6, and the inclined block 6 drives the two limit rods 5 to move toward each other. The interior of the clamp housing 1 is provided with sliding grooves located on the upper and lower sides of the limit rod 5. The sliding grooves are used to limit the limit rods 5 in the vertical direction when they move toward each other. The spring rod 11 is divided into a rod body and a spring sleeved on the outside thereof. The two ends of the spring are fixedly connected to the clamp housing 1 and the first connecting rod 7 respectively.

[0027] It is fixedly connected to the first connecting rod 7 through a spring, which is used to squeeze the first connecting rod 7 and keep it moving toward the second connecting rod 8. When the pressure on the pressure block 10 is released, the first connecting rod 7 is reset under the action of the elastic force of the spring rod 11, thereby releasing the squeezing of the inclined block 6, and then the two inclined blocks 6 are reset under the action of the elastic force of the spring sheet 12, thereby driving the two limit rods 5 to move in opposite directions, and then the gasket 4 drives the arc block 3 to move in the opposite direction, and releases the grip on the suture needle.

[0028] It is worth noting here that: a cavity is provided inside the clamp housing 1 on one side of the limit rod 5, which is used to facilitate the two limit rods 5 to move toward each other, and a groove is provided on the inner wall of the needle hole 2, which is used to facilitate the two arc blocks 3 to move toward each other. When the limit rod 5 abuts against the inner wall of the clamp housing 1, the arc block 3 drives the two gaskets 4 to abut against each other and form a circle, thereby grabbing the suture needle.

[0029] The working principle and use process of the utility model are as follows: during surgery, the medical staff puts the suture needle into the needle hole 2, and then presses the pressure block 10 toward the inside of the clamp housing 1, thereby driving the two third connecting rods 9 to move toward each other, and then driving the first connecting rod 7 to move downward through the second connecting rod 8. While the first connecting rod 7 moves downward, the two inclined blocks 6 are squeezed, so that the inclined blocks 6 drive the two limit rods 5 to move toward each other, and then drive the two arc blocks 3 and the gaskets 4 thereon to move toward each other, and then the two gaskets 4 respectively clamp the surface of the suture needle in the needle hole 2 to keep it stable.
