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
The present invention relates to a kind of medical tourniquet.
Background technology
Hysteromyoma is the female sex organs most common tumor, and the women of child-bearing age's sickness rate is about 20-25%, and is the trend of rising with the increase at age.At present, operation still is the main treatment means of hysteromyoma.The hysteromyoma evidement have keep patient's reproductive function, avoid influencing ovarian function, guarantee patient's physical and mental health, advantage such as improve the quality of living, especially the carrying out of muscular tumor evidement (LM) under the peritoneoscope, not only remove muscular tumor, and compare with abdominal, have postoperative pain light, recover advantage such as fast, that the hospital stays is short; Along with the development of laparoscopic technique and the improvement of operating theater instruments, make that the hysteromyoma evidement is popularized under the peritoneoscope.But, under peritoneoscope in the hysteromyoma evidement, although widely used tourniquet is of a great variety, knot is not tight, the shortcoming of dismounting difficulty but the ubiquity tourniquet is pricked, exist intraoperative hemorrhage more, influence surgical field of view, increase the involutory difficulty of flesh layer when sewing up, and cause defectives such as postoperative anemia and the sick rate increase of postoperative.
Summary of the invention
The objective of the invention is above-mentioned deficiency, a kind of medical tourniquet be provided at prior art, it have prick knot firmly, convenient disassembly advantage, avoid patient's massive blood loss in art.
For achieving the above object, a kind of medical tourniquet of the present invention comprises pedestal, drawstring, it is characterized in that an end of drawstring is fixed on the pedestal, and the other end connects firmly a puncturing head, also connects firmly one section sawtooth on drawstring; In pedestal, also be provided with the drawstring passage, the inner chamber that communicates with the drawstring passage, by the rotating shaft on the pedestal one movable snap close is installed in inner chamber, side at the close drawstring passage of movable snap close is installed with sawtooth, sawtooth on sawtooth on the drawstring and the movable snap close matches when assembling, the direction of motion of drawstring in the drawstring passage was opposite when the incline direction of sawtooth was with snap close on the drawstring, on the movable snap close on the incline direction of sawtooth and the drawstring incline direction of sawtooth opposite, be provided with the pin hole that communicates on movable snap close and pedestal, a latch is loaded in the pin hole of pedestal and movable snap close.
During use, puncturing head is passed in the drawstring passage, sawtooth and the sawtooth on the movable snap close on the drawstring is engaged at this moment, drawstring can only be unidirectional mobile in the drawstring passage, can prevent that drawstring from withdrawing from the drawstring passage, drawstring and pedestal are formed ring-type, and the pulling drawstring is to suitable position, can lock objects such as cervix uteri, with the uterine artery bloodstream blocking; When extracting latch, movable snap close is left drawstring, the sawtooth on the drawstring separates with sawtooth on the movable snap close, can oppositely withdraw from drawstring, have prick knot firmly, convenient disassembly advantage.
As a further improvement on the present invention, one section the lopsidedness to movable snap close of described drawstring passage between its outlet and movable snap close can make drawstring be adjacent to movable snap close, makes the two sawtooth interlock tightr.
As a further improvement on the present invention, described latch is connected on the pedestal by frenulum, can prevent latch and base-separation, avoids latch to leave in patient's body, accident surgery occurs.
In sum, the present invention have prick knot firmly, convenient disassembly advantage, avoid patient's massive blood loss in art.
Description of drawings
Fig. 1 is in the front view of snap close state for the embodiment of the invention.
Fig. 2 is in the front view of opening for the embodiment of the invention.
The specific embodiment
The present invention is further detailed explanation for knot meeting accompanying drawing below.
As shown in Figure 1, this medical tourniquet comprises pedestal 1, drawstring 2, and an end of described drawstring 2 is fixed on the pedestal 1, and the other end connects firmly a puncturing head 3, also connects firmly one section sawtooth on drawstring 2; In pedestal 1, also be provided with the drawstring passage, the inner chamber 4 that communicates with the drawstring passage, by the rotating shaft on the pedestal 15 a movable snap close 6 is installed in inner chamber 4, side at movable snap close 6 close drawstring passages is installed with sawtooth, one section the lopsidedness to movable snap close of described drawstring passage between its outlet and movable snap close 6, sawtooth on sawtooth on the drawstring 2 and the movable snap close matches when assembling, the direction of motion of drawstring 2 in the drawstring passage was opposite when the incline direction of sawtooth was with snap close on the drawstring 2, on the movable snap close 6 on the incline direction of sawtooth and the drawstring 2 incline direction of sawtooth opposite, on movable snap close 6 and pedestal 1, be provided with the pin hole that communicates, one latch 7 is loaded in the pin hole of pedestal 1 and movable snap close 6, and described latch 7 is connected on the pedestal 1 by frenulum; During use, puncturing head 3 is passed in the drawstring passage, sawtooth and the sawtooth on the movable snap close 6 on the drawstring 2 is engaged at this moment, drawstring 2 can only be unidirectional mobile in the drawstring passage, can prevent that drawstring 2 from withdrawing from the drawstring passage, drawstring 2 is formed ring-type with pedestal 1, and pulling drawstring 2 is to suitable position, can lock objects such as cervix uteri, with the uterine artery bloodstream blocking.
As shown in Figure 2, when extracting latch 7, movable snap close 6 is left drawstring 2, the sawtooth on the drawstring 2 separates with sawtooth on the movable snap close 6, can oppositely withdraw from drawstring 2.
