Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a catheter fixator for gastrointestinal surgery. Background Art

[0002] With the development of science and technology, in gastrointestinal surgery clinics, there is an increasing tendency to reduce the number of traditional open surgeries. As a commonly used medical method in gastrointestinal surgery clinical operations, catheter intervention therapy is the basic technical prerequisite for minimally invasive gastrointestinal surgery.

[0003] As shown in the instruction manual appendix Figure 4 As shown, the existing catheter clamping device needs to be clamped and fixed by screw rotation. The process of screw rotation is relatively slow, which delays the operation time of medical staff and has low efficiency. Therefore, we propose a catheter fixator for gastrointestinal surgery. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing catheter clamping device has low efficiency in use and delays the operation time of medical staff;

[0005] To solve the above technical problem, the technical solution provided by the utility model is: a catheter fixator for gastrointestinal surgery, including a fixing plate, a right bandage and a left bandage. It is characterized in that the fixing plate is in an arc structure, and ear plates are provided on both sides of the fixing plate. Through grooves are opened in the ear plates. The through groove on the right side of the fixing plate is fixedly connected with the right bandage, and the through groove on the left side of the fixing plate is fixedly connected with the left bandage. A connecting shell is provided at the front end of the fixing plate. A sliding rod penetrates through the connecting shell. An upper clamping block is provided at the bottom end of the sliding rod. A cavity is provided in the connecting shell. A spring is provided on the outer wall of the sliding rod located in the cavity.

[0006] As an improvement, a notch and a lower groove are opened on the fixing plate, and an upper groove is provided at the bottom of the upper clamping block.

[0007] As an improvement, the connecting shell is in a U-shaped structure and is connected to the fixing plate on one side. A reserved opening matching the upper clamping block is provided at the bottom end of the connecting shell.

[0008] As an improvement, a limiting disk is further provided on the outer wall of the sliding rod located in the cavity, and the limiting disk is arranged at the inner top of the connecting shell. The sliding rod is slidably arranged with the limiting disk. The bottom end of the spring is fixedly connected to the top of the upper clamping block, and the top end of the spring is fixedly connected to the limiting disk.

[0009] As an improvement, a handle is provided at one end of the sliding rod away from the upper clamping block, and anti-slip lines are provided on the outer wall of the handle.

[0010] As an improvement, a magic tape one is provided at one end of the left bandage away from the ear plate, and a magic tape two matching the magic tape one is provided on one side of the right bandage.

[0011] The advantages of the present utility model compared with the existing technology are as follows: Through the arrangement of the connecting shell, sliding rod, and spring, medical staff can directly pull the handle. The handle drives the sliding rod to move outwards, and the spring contracts, then the catheter can be placed. When the handle is released, the spring drives the sliding rod to automatically open by its own elasticity, and the upper clamp clamps the catheter, reducing the process of medical staff rotating the thread and improving the fixing efficiency of the catheter.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] The problems of the existing technology are fully interpreted in the technical background of this application, and there are no problems of generalization or overarching. In the following detailed description of the utility model and the specific implementation manners, the problems to be solved by this application are specifically described, clarifying the technical problems that the technical solutions need to solve, and determining that the technical solutions of this application have beneficial effects compared with the objective existing technology.

[0019] Please refer to Figures 1-3 , an embodiment provided by the present utility model:

[0020] A catheter fixator for gastrointestinal surgery, comprising a fixing plate 1, a right bandage 3 and a left bandage 4. The fixing plate 1 is of an arc-shaped structure, and ear plates 2 are provided on both sides of the fixing plate 1. Through grooves are formed in the ear plates 2. The through groove on the right side of the fixing plate 1 is fixedly connected to the right bandage, and the through groove on the left side of the fixing plate 1 is fixedly connected to the left bandage 4. One end of the left bandage 4 away from the ear plate 2 is provided with a first magic tape, and one side of the right bandage is provided with a second magic tape matching the first magic tape, which is convenient for the connection between the left bandage 4 and the right bandage 3. A connection shell 7 is provided at the front end of the fixing plate 1. A sliding rod 9 penetrates through the connection shell 7. A clamping block 8 is provided at the bottom end of the sliding rod 9. A cavity 701 is provided in the connection shell 7. A spring 10 is provided on the outer wall of the sliding rod 9 located in the cavity 701. One end of the sliding rod 9 away from the clamping block 8 is provided with a handle 11. The outer wall of the handle 11 is provided with anti-slip lines 1101, and the anti-slip lines increase the anti-slip effect;

[0021] Combined with the attached Figure 1 , a notch 5 and a lower groove 6 are formed on the fixing plate 1. An upper groove is provided at the bottom of the clamping block 8.

[0022] Combined with the attached Figure 2 , the connection shell 7 is of a U-shaped structure and is connected to the fixing plate 1 on one side. A reserved opening matching the clamping block 8 is provided at the bottom end of the connection shell 7. A limiting disk 901 is further provided on the outer wall of the sliding rod 9 located in the cavity 701, and the limiting disk 901 is arranged at the inner top of the connection shell 7. The sliding rod 9 is slidably arranged with the limiting disk 901. The bottom end of the spring 10 is fixedly connected to the top of the clamping block 8, and the top end of the spring 10 is fixedly connected to the limiting disk 901. The movement of the clamping block is realized through the elasticity of the spring;

[0023] First, medical staff wrap the left bandage 4 and the right bandage 3 around the patient's body, specifically close to the minimally invasive puncture area. Pull the handle 11, and the handle 11 drives the sliding rod 9 to move upward. The spring on the sliding rod 9 contracts under its own elastic force. The sliding rod moves upward, and the clamping block 8 moves upward. Move the catheter extending from the patient's body from the notch 5 to the lower groove 6. Slowly release the handle, and the spring 10 automatically expands by its own elasticity. The sliding rod 9 drives the clamping block 8 to move downward, thereby clamping the catheter and realizing the fixing effect on the catheter;
