Abdomen expander for spinal surgery

Abstract

The invention discloses an abdomen expander for a spinal surgery. The abdomen expander comprises a support frame, wherein the support frame is formed by connecting four arc supports of which the sizesare one-fourth round end to end; two adjustment mechanisms and two guiding mechanisms are sequentially arranged at four connection parts of the support frame in the circumferential direction of the support frame; a base is arranged at the lower ends of the arc supports; statlocks adhered with the skin of a patient are arranged at the lower end of the base; T-shaped slots are formed in the arc supports in the circumferential direction; a plurality of circular arc limiting slots are formed in the side surfaces of the T-shaped slots; pull hook bases are arranged in the T-shaped slots; ejector blocks are arranged on the side surfaces of the pull hook bases; a spring is arranged between the corresponding ejector block and the corresponding pull hook base; support rods are arranged at the upperends of the pull hook bases in an extending manner; the support rods are matched and fixed with the circular arc limiting slots under an effect of the springs; sleeves are arranged at the upper endsof the support rod; one end of the corresponding sleeve is connected with an arc limiting block through a connecting rod; an adjusting sleeve is arranged between the corresponding sleeve and the corresponding arc limiting block; the adjusting sleeves are in threaded fit with pull hooks; guiding grooves are formed in the pull hooks; the guiding grooves are matched with guiding blocks arranged on the inner sides of the sleeves.

Description

technical field [0001] The invention relates to a surgical expander, in particular to an abdominal expander for spinal surgery. Background technique [0002] In recent years, surgery has developed rapidly, from the initial limb surgery to the later thoracic cavity surgery, and even the controversial head transplant surgery. Spine, especially lower thoracic and lumbar operations, sometimes require an anterior or lateral anterior approach, transabdominal or transperitoneal. Under the background of these developed technologies, there is a very unsuitable phenomenon. One operation often requires several assistants to stand beside the operating table for several hours, just to open the surgical incision for the surgeon to perform the operation. Especially in the gynecology department, when the patient's abdomen is operated on through a cross incision, this most primitive operation method is more common, because the operation incision is larger than other operations, and several ...

Problems solved by technology

Under the background of these developed technologies, there is a very unmatched phenomenon. One operation often requires several assistants to stand beside the operating table for several hours, just to open the surgical incision for the surgeon to perform the operation. This is the most primitive operation method in gynecological department when using cross incision to operate on the patient's abdomen, because the operation incision is larger than other operations, and several assistants are often required to pull the incision from different directions. This method has disadvantages It is obvious: (1) a waste of human resources; (2) occupying the operating space and hindering the operation of the surgeon; (3) keeping the retractor posture for a long time is also a great test for the endurance of the medical staff; (4) affecting the surgeon The tacit understanding between the assistant and the assistant is relatively high, and the grasp of the distance and strength of the retractor also requires a certain experience. Therefore, it is extremely necessary to design a surgical expander
