Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a hemostat for clinical surgery. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. Hemostats, as one of the medical devices, are commonly used to help medical personnel perform hemostasis operations.

[0003] However, when performing hemostasis operations in general surgery clinical operations, hemostatic clips are mostly used for hemostasis. However, existing hemostatic clips are small in size, inconvenient to operate, and the clamping force cannot be adjusted, which has poor practicality. Utility Model Content

[0004] The utility model aims to provide a hemostat for clinical surgery to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a clinical surgical hemostat, comprising an upper clamp arm and a lower clamp arm, a fixed arm is provided at one end of the upper clamp arm, and two triangular blocks are provided on the side wall of the fixed arm, and the two triangular blocks are rotatably connected to the end of the lower clamp arm through a rotating shaft, and the upper clamp arm and the lower clamp arm are provided with detachable hemostatic chucks at one end away from the fixed arm, and the upper and lower hemostatic chucks are distributed correspondingly, and a force applying arm is provided on the back of the lower clamp arm, and the force applying arm and the fixed arm are connected through a spring and a pressure regulating structure.

[0006] Preferably, the fixed arm and the upper clamping arm are vertically distributed, and the lower clamping arm and the force applying arm are both arc-shaped structures.

[0007] Preferably, the ends of the upper clamp arm and the lower clamp arm are both provided with slots, and the ends of the hemostatic clamp are provided with plug blocks distributed corresponding to the slots, and the size of the plug blocks matches the size of the slots.

[0008] Preferably, the side walls of the upper clamp arm and the side walls of the lower clamp arm are both provided with through holes penetrating the slots, and the side walls of the insert block are provided with mounting holes distributed corresponding to the through holes, and the mounting holes are fixedly connected to the through holes by screws.

[0009] Preferably, the hemostatic chuck is a pointed structure, and a plurality of staggered anti-slip teeth are provided on opposite sides of the upper and lower hemostatic chucks.

[0010] Preferably, the pressure regulating structure includes a stud and a knob, one end of the stud is fixedly connected to the back of the force arm, one end of the knob is provided with a threaded cavity threadedly connected to the stud, the other end of the knob is connected to a spring, and the surface of the knob is provided with anti-slip grooves.

[0011] Preferably, a groove is provided on the side wall of the fixed arm, and the end of the spring is fixedly connected to the inner wall of the groove.

[0012] The utility model is a clinical surgical hemostat with the following advantages:

[0013] 1. The utility model clamps and fixes through the elastic force of the spring, and the clamping force is relatively strong. Therefore, the size of the clamping force can be changed by turning the knob, thereby changing the distance between the knob and the force-applying arm, while maintaining the existing holding force, without loosening or being too tight, thereby not causing damage to the skin, which is beneficial for use by medical staff. A lever structure is formed between the upper clamping arm and the fixed arm, the lower clamping arm and the force-applying arm, making the operation simple and labor-saving. Only the force-applying arm needs to be aligned with both sides of the wound and released, and the skin on both sides of the wound can be clamped under the elastic force of the spring, thereby achieving the effect of hemostasis. The entire hemostasis process is quick and rapid, which is beneficial for the operation.

[0014] 2. Through the cooperation of the plug block and the slot, it is convenient to connect the hemostatic chuck with the upper clamp arm and the lower clamp arm, so as to facilitate the replacement of the hemostatic chuck, thereby saving costs. Through the setting of the anti-slip teeth, the hemostat can be effectively prevented from sliding during the process of clamping the blood vessel, thereby improving stability.
