Abstract

The invention discloses a pair of operating forceps with a negative pressure suction function. The pair of operating forceps comprises forcep handles, forcep levers and a forcep head, wherein the forcep handles are connected with the forcep head through the forcep levers; the forcep head comprises a main claw and an auxiliary claw hinged to the main claw; the forcep handles comprise a fixed handle and a movable handle hinged to the fixed handle; a connector connected with a negative pressure system is arranged on the fixed handle, a handle negative pressure channel communicated with the connector is arranged in the fixed handle in a hidden manner, a lever negative pressure channel communicated with the handle negative pressure channel is arranged in one forcep lever, and a head negative pressure channel communicated with the lever negative pressure channel is arranged in the main claw in a hidden manner; a negative pressure hole communicated with the head negative pressure channel is further formed in the main claw; the fixed handle, the corresponding forcep lever and the main claw are sequentially fixedly connected; the movable handle is connected with the auxiliary claw through a pull rod penetrating through an inner cavity of one forcep lever, and the movable handle pulls the pull rod to control the auxiliary claw and the main claw to be closed and opened. According to the technical scheme, tissue can be clamped under the joint action of mechanical clamping and negative pressure clamping, and the pair of operating forceps has the advantages of controllability of clamping force, little damage to tissue, adaptability to various soft tissue organs, safe and precise operation and the like.

Description

technical field [0001] The invention relates to a laparoscopic surgical instrument in the medical field, in particular to a surgical forceps with negative pressure suction function. Background technique [0002] Minimally invasive surgery has been widely used clinically in recent years, and it has been paid attention by both clinicians and patients because of its minimally invasive injury, less bleeding, and quick postoperative recovery. [0003] There are many kinds of biological soft tissues in the abdominal cavity, with large areas, delicate tissue structures, sticky, slippery and flexible surfaces. In laparoscopic surgery, forceps and suction are the most commonly used minimally invasive surgical instruments. [0004] Existing laparoscopic surgical forceps generally operate on tissues through the mechanical clamping of two jaws, and there are problems such as laborious operation when clamping and pulling tissues, and easy slippage or damage. [0005] Negative pressure ...
