Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is described in further detail.

[0012] As shown in Figure 1, the medical tourniquet includes a base 1 and a drawstring 2. One end of the drawstring 2 is fixedly connected to the base 1, and the other end is fixedly connected to a puncture head 3. A section of sawtooth is fixedly connected; in the base 1, there is also a drawstring channel and an inner chamber 4 communicated with the drawstring passage, and a movable lock 6 is installed in the inner chamber 4 through the rotating shaft 5 on the base 1, and the movable lock The buckle 6 is fixed with serrations near the side of the drawstring passage, and a section of the drawstring passage between its exit and the movable lock 6 is inclined to the side of the movable lock, and the sawtooth on the drawstring 2 is aligned with the movable lock. The sawtooth on the buckle is matched during assembly. The inclination direction of the sawtooth on the draws...

Abstract

The present invention discloses a medical tourniquet which comprises a base and a strip. The invention is characterized in that one end of strip is fixedly connected with the base, and the other end is fixedly connected with a puncture head. The strip is also fixedly connected with a segment of sawtooth. The base is internally provided with a strip channel and in internal cavity communicated withthe strip channel. A movable lock catch is installed in the internal cavity through a rotating shaft on the base. Sawteeth are fixedly installed at one side of movable lock catch next to the strip channel. The tilt direction of sawteeth on the strip is opposite to the moving direction of strip in the strip channel in locking. The tilt direction of sawteeth on movable lock catch is opposite with the tilt direction of sawteeth on the strip. Communicated bolt holes are installed on the movable lock catch and the base. One bolt is installed in the bolt holes of base and movable lock catch. The medical tourniquet of the invention has the advantages of firm bundling and convenient detachment and prevents the large-amount blood loss of patient in surgery.

Description

technical field [0001] The invention relates to a medical tourniquet. Background technique [0002] Uterine fibroids are the most common tumors of female genitalia. The incidence rate of women of childbearing age is about 20-25%, and it is on the rise with the increase of age. At present, surgery is still the main treatment for uterine fibroids. Myomectomy has the advantages of preserving the reproductive function of patients, avoiding affecting ovarian function, ensuring the physical and mental health of patients, and improving the quality of life. Especially, the development of laparoscopic myomectomy (LM) not only removes myoma, but also Compared with open surgery, it has the advantages of less postoperative pain, faster recovery, and shorter hospital stay. With the development of laparoscopic technology and the improvement of surgical instruments, laparoscopic myomectomy has become popular. However, in laparoscopic myomectomy, although there are many types of tournique...
