Description

TECHNICAL FIELD

[0001] The utility model belongs to the medical equipment technical field, more specifically, especially relate to a rotatable repeatable open and close soft tissue clamp. BACKGROUND

[0002] The tissue clamp is a medical instrument for tissue traction, ligation and fixation in surgery. The tissue clamp is made of stainless steel wire and can be divided into straight type and bent type. The straight type tissue clamp is used for clamping tissue, and the bent type tissue clamp is used for clamping tubular tissue such as blood vessels. The tissue clamp has the characteristics of good elasticity, large tension, no pollution, no deformation, high temperature resistance, corrosion resistance, no magnetism and the like, and is widely used in clinical surgery.

[0003] Based on the above, it is found that the following problems exist: the existing soft tissue clamp has a single function and cannot rotate and repeatedly open and close. When the angle of clamping needs to be adjusted in some difficult-to-operate positions, the angle of the whole clamp can only be adjusted manually as a whole, which is prone to limited position and change of clamping force of the clamp due to hand rotation, resulting in inconvenience in use.

[0004] Therefore, in view of the above, the existing structure and defects are studied and improved, and a rotatable repeatable open and close soft tissue clamp is provided to achieve a more practical value. UTILITY MODEL CONTENTS

[0005] In order to solve the above technical problems, the utility model provides a rotatable repeatable open and close soft tissue clamp to solve the problem that the angle of clamping can only be adjusted manually as a whole when the angle of clamping needs to be adjusted in some difficult-to-operate positions, which is prone to limited position.

[0006] The utility model provides a rotatable repeatable open and close soft tissue clamp, which is achieved by the following specific technical means:

[0007] A rotatable, repetitively opening and closing soft tissue clip includes a grip sleeve. A first connecting sleeve is rotatably connected to the bottom of the grip sleeve, and a second connecting sleeve is rotatably connected to the top of the grip sleeve. The first and second connecting sleeves are connected to each other at one end inside the grip sleeve. A lifting rod is movably connected through one side of the second connecting sleeve. A nylon rope is fixed to the bottom of the middle of the lifting rod, and a first support plate is fixed to the bottom of the nylon rope. First connecting rods are fixed to both sides of the bottom of the first connecting sleeve, with the bottom ends of the two first connecting rods extending outside the first connecting sleeve. A first connecting shaft is fixed to the middle of the opposite side of the two first connecting rods. A first clamping rod and a second clamping rod are rotatably connected to the outer wall of the first connecting shaft. A second connecting rod is hinged to the top of both the first and second clamping rods. A common second connecting shaft movably passes through the tops of the two second connecting rods. A first spring is fixed to the top of the first support plate. Limiting mechanisms are provided at the top of the outer wall of the grip sleeve and the bottom of the second connecting sleeve.

[0008] Furthermore, a second support plate is fixed at the middle of the top of the inner wall of the first connecting sleeve, the nylon rope moves through the middle of the second support plate, and the first spring is movably sleeved on the outer wall of the nylon rope and its top end is fixed to the bottom of the second support plate.

[0009] Furthermore, the limiting mechanism includes a limiting ratchet and a hinge seat. The limiting ratchet is fixed to the bottom of the outer wall of the second connecting sleeve, and the outer wall of the limiting ratchet is provided with multiple slots in a circumferentially equidistant manner.

[0010] Furthermore, one side of the hinge seat is fixed to the top of the outer wall of the grip sleeve, a support rod is hinged to the middle of the hinge seat, and the support rod is bent. A second spring is fixed to the bottom of the support rod and the middle of the second connecting sleeve.

[0011] Furthermore, a locking block is fixed to the top of the support rod near the second connecting sleeve. The locking block is used in conjunction with the locking groove of the limiting ratchet, and both the outer wall of the locking block and the locking groove are arc-shaped.

[0012] Furthermore, each of the bottom ends of the first support plate is fixed with a hanging lug, and the two ends of the second connecting shaft are respectively fixed to the two hanging lugs at the bottom of the first support plate.

[0013] Furthermore, the second connecting sleeve has through grooves on both sides, the lifting rod is slidably connected to the grooves, and the bottom of both ends of the lifting rod on the outer wall of the second connecting sleeve has arc-shaped grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, by pressing the bottom of the support rod with one finger holding the handle sleeve, the locking block is separated from the limiting ratchet. The other hand rotates the second connecting sleeve to drive the second connecting sleeve to rotate. After rotation, the finger pressing the support rod is released, the second spring releases its elastic potential energy, and the top of the support rod moves towards the second connecting sleeve. The support rod limits the second connecting sleeve, thereby achieving the effect that the clamp itself can adjust the clamping angle. At the same time, after adjustment, it has a self-locking function to prevent the angle from changing arbitrarily during use.

[0016] 2. In use, this utility model involves pressing the top of the second connecting sleeve with the thumb, then placing the index and middle fingers in the arc-shaped groove of the lifting rod, and pulling the lifting rod upward to slide it in the groove. At this time, the first spring is compressed, the first support plate moves upward, and the bottom ends of the first and second clamping rods move towards the center to clamp the soft tissue. After clamping, the index and middle fingers are released, the first spring releases its elastic potential energy, causing the first support plate to return to its original position, and the first and second clamping rods open. This achieves repeated clamping and uses a buffer device to reduce wear and stress concentration during the opening and closing process. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a rotatable, reversibly openable and closeable soft tissue clip, including a grip sleeve 1. A first connecting sleeve 2 is rotatably connected to the bottom of the grip sleeve 1, and a second connecting sleeve 3 is rotatably connected to the top of the grip sleeve 1. The first connecting sleeve 2 and the second connecting sleeve 3 are connected to each other at one end inside the grip sleeve 1. A lifting rod 14 is movably connected through one side of the second connecting sleeve 3. A nylon rope 13 is fixed to the bottom of the middle of the lifting rod 14. A first support plate 10 is fixed to the bottom of the nylon rope 13. First connecting rods 4 are fixed to both sides of the bottom of the first connecting sleeve 2. The bottom ends of the two first connecting rods 4 extend outside the first connecting sleeve 2. A first connecting shaft 7 is fixed to the middle of the opposite side of the two first connecting rods 4. A first clamping rod 5 and a second clamping rod 6 are rotatably connected to the outer wall of the first connecting shaft 7. A second connecting rod 8 is hinged to the top of the first clamping rod 5 and the second clamping rod 6. A common second connecting shaft 9 is movably passed through the top of the two second connecting rods 8. A first spring 11 is fixed to the top of the first support plate 10. Limiting mechanisms are provided at the top of the outer wall of the grip sleeve 1 and the bottom of the second connecting sleeve 3.

[0028] The second support plate 12 is fixed in the middle of the top of the inner wall of the first connecting sleeve 2. The nylon rope 13 moves through the middle of the second support plate 12. The first spring 11 is movably sleeved on the outer wall of the nylon rope 13 and its top end is fixed to the bottom of the second support plate 12. The first support plate 10 is supported by the first spring 11, so that when it is not affected by external force, the first support plate 10 is located at the bottom of the first connecting sleeve 2. At this time, the bottom ends of the first clamping rod 5 and the second clamping rod 6 are open.

[0029] The limiting mechanism includes a limiting ratchet 16 and a hinge seat 17. The limiting ratchet 16 is fixed to the bottom of the outer wall of the second connecting sleeve 3. The outer wall of the limiting ratchet 16 has multiple slots equidistantly arranged in a circular shape. The limiting mechanism limits the second connecting sleeve 3, thereby limiting the first connecting sleeve 2, the first clamping rod 5, and the second clamping rod 6.

[0030] The hinge seat 17 is fixed to the top of the outer wall of the grip sleeve 1 on one side. A support rod 18 is hinged to the middle of the hinge seat 17 and the support rod 18 is bent. A second spring 19 is fixed to the bottom of the support rod 18 and the middle of the second connecting sleeve 3. The elastic potential energy is released by the second spring 19, so that the top of the support rod 18 moves toward the second connecting sleeve 3 when there is no external force.

[0031] The support rod 18 has a locking block 20 fixed at the top near the second connecting sleeve 3. The locking block 20 is used in conjunction with the slot of the limiting ratchet 16. The outer wall of the locking block 20 and the slot are both arc-shaped. When there is no external force, the locking block 20 is located inside the slot. The position of the second connecting sleeve 3 is fixed. When it is necessary to rotate the position of the first connecting sleeve 2, the first clamping rod 5 and the second clamping rod 6, press the bottom of the support rod 18 with one finger holding the handle sleeve 1 to separate the locking block 20 from the limiting ratchet 16. Then, rotate the second connecting sleeve 3 with the other hand to drive the second connecting sleeve 2 to rotate. After rotation, release the finger pressing the support rod 18.

[0032] The first support plate 10 has two hanging ears fixed at the bottom center on both sides. The two ends of the second connecting shaft 9 are fixed to the two hanging ears at the bottom of the first support plate 10 respectively. The first spring 11 is connected to the second connecting rod 8 through the first support plate 10 and the second connecting shaft 9.

[0033] The second connecting sleeve 3 has sliding grooves 15 extending through both sides. The lifting rod 14 is slidably connected to the sliding grooves 15. The bottom of both ends of the lifting rod 14 on the outer wall of the second connecting sleeve 3 has arc-shaped grooves. When it is necessary to clamp the soft tissue with the first clamping rod 5 and the second clamping rod 6, press the top of the second connecting sleeve 3 with your thumb, and then place your index and middle fingers in the arc-shaped grooves of the lifting rod 14. Pull the lifting rod 14 upward to slide it in the sliding grooves 15. At this time, the first spring 11 is compressed, and the first support plate 10 moves upward and the bottom ends of the first clamping rod 5 and the second clamping rod 6 move towards the center to clamp the soft tissue.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the user first presses the top of the second connecting sleeve 3 with their thumb, then places their index and middle fingers in the arc-shaped groove of the lifting rod 14 and pulls the lifting rod 14 upwards to slide it in the sliding groove 15. At this time, the first spring 11 is compressed, and the first support plate 10 moves upwards. As the first support plate 10 moves upwards, the angle between the two second connecting rods 8 decreases, simultaneously causing the tops of the first clamping rod 5 and the second clamping rod 6 to move closer together. The bottom ends of the first clamping rod 5 and the second clamping rod 6 move closer together to clamp the soft tissue. After clamping, the index and middle fingers are released, and the first spring 11 releases its elastic potential energy, causing the first support plate to... 10. Reset, the first clamping rod 5 and the second clamping rod 6 open. When it is necessary to rotate the first connecting sleeve 2, the first clamping rod 5 and the second clamping rod 6, press the bottom of the support rod 18 with one finger holding the handle sleeve 1, so that the locking block 20 is separated from the limiting ratchet 16. Use the other hand to rotate the second connecting sleeve 3 to drive the second connecting sleeve 2 to rotate. After rotation is completed, release the finger pressing the support rod 18. The second spring 19 releases elastic potential energy, so that when there is no external force, the top of the support rod 18 moves towards the second connecting sleeve 3. The support rod 18 limits the second connecting sleeve 3, preventing the second connecting sleeve 3 and the first connecting sleeve 2 from rotating at will.
