Turnover needle holder for space-limited surgery

Abstract

The invention discloses a turnover needle holder for a space-limited surgery. The turnover needle holder is characterized by comprising a turnover function assembly and a clamping releasing function assembly, wherein the turnover function assembly is characterized by comprising 1 (small wheel assembly), 2 (casing assembly), 3 (bull wheel assembly), 8 (turnover ropes), 4 (fixing handle), 5 (movinghandle) and 7( needle holding assembly). The clamping releasing function assembly is characterized by comprising 6 (art knife adjusting block), 9 (needle holding rope) and 7 (needle holding assembly).The turnover needle holder can realize internal needle turnover motion by external control, and turnover of the entire needle holder is not needed. The turnover needle holder is suitable for occasions where the operation space is narrow, and the needle holder is not allowed to do big-motion moving and turning over, such as a transvaginal surgery. The turnover needle holder can reduce the operation difficulty for suturing for the space-limited surgery, surgery time can be shortened, the surgery experience of doctors and patients can be improved, and guarantee is increased for life health of the patients.

Description

technical field [0001] The invention relates to a reversible needle holder for operations with limited space, and is especially suitable for operations with narrow operating spaces, such as vaginal operations. Background technique [0002] The so-called vaginal surgery is to use the natural orifice of the vagina to perform surgery. [0003] Since cesarean section is less painful than normal delivery, it has been highly praised in recent years. [0004] However, the healing of uterine incision may be uneven due to incision location, incision suture density or improper tightness, infection and other reasons, and diverticulum is uterine scar diverticulum. [0005] Studies have shown that the probability of uterine scar diverticulum in patients with more than three caesarean sections is 100%. [0006] Patients with cesarean scar diverticulum mainly present with abnormal vaginal bleeding, secondary infertility, chronic pelvic pain, and abdominal pain during menstruation, among ...

Problems solved by technology

[0019] But for vaginal surgery, there is no such horizontal space

[0020] The existing needle holder has no new design for many years. The structure of the needle holder is similar to the X shape, that is, the scissors and fork type. Large, and therefore have greater limitations in vaginal surgery, and urgently need improvement

When the position of the moving block moves to its lower surface against the locking teeth, the locking teeth are not pressed tightly, but rely on their own elasticity to break away from the locking groove, so there is no locking.
