Inflatable scalp hemostatic clip bar

Abstract

The invention provides an inflatable scalp hemostatic clip bar, which comprises clip bodies, wherein the clip body has a C-shaped cross section. An elastic piece extending from the bottom of a clip port to the opening of the clip port is disposed on the inner wall of the clip port of the clip body, and the elastic piece extends toward the opening of the clip port and the end portion is provided with a blocking piece. The blocking piece extends toward one of the inner wall of the clip body adjacent to the elastic piece and is wrapped to the outside of the clip body to adhere to the outer wall of the clip body, so that an expansion cross section is formed between the blocking piece, the elastic piece and the inner wall of the clip body; the clip bodies are multiple, the adjacent clip bodiesare connected by joint points, and the joint points are located at a center position of the side wall of the C-shaped section of the clip body on the side close to the elastic piece; and an inflationair bag is interposed in the longitudinal direction of each clip body in the expansion cross section. The clip bar has the advantages of quick installation, good hemostatic effect, adjustable clip force and adjustment according to the curvature of a scalpel edge.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an inflatable scalp hemostatic clip. Background technique [0002] Craniotomy, also known as craniotomy, is generally performed clinically in cases of craniocerebral injury or removal of a patient's brain tumor. Craniotomy generally cuts a U-shaped opening on the scalp of the patient's diseased part, then makes several holes in the skull, takes out the corresponding skull, performs medical operations, and then puts it back into the skull to suture the wound; during craniotomy , you need to use a scalpel to cut the scalp according to the predetermined position. Because the human scalp is rich in blood vessels, it is necessary to place a hemostatic clip along the incision to stop bleeding after the scalp is cut. The existing hemostatic clip is C-shaped, and it is stretched with surgical forceps After opening, clip the scalp incision into the jaw, and use the elasticity of the hemost...

AI Technical Summary

Problems solved by technology

Craniotomy generally cuts a U-shaped opening on the scalp of the patient's sick part, and then makes a few holes in the skull, takes out the corresponding skull, performs medical operations, and then puts it back into the skull to suture the wound; during craniotomy , you need to use a scalpel to cut the scalp according to the predetermined position. Because the human scalp is rich in blood vessels, it is necessary to place a hemostatic clip along the incision to stop bleeding after the scalp is cut. The existing hemostatic clip is C-shaped, and it is stretched with surgical forceps. After opening, clip the scalp incision into the jaw, and use the elasticity of the hemostatic clip to clamp the scalp incision to block the blood circulation to achieve the purpose of hemostasis. However, because the existing C-shaped clips need to be installed one by one during installation, it is time-consuming and laborious. At the same time, its clamping force has been determined during production, and it is difficult to adjust it for people with different scalp thicknesses. Therefore, it is easy to clamp too tightly or too loosely, which will lead to long-term tissue ischemia and affect postoperative recovery.
