Problems solved by technology

The traditional surgical retractor is composed of a rod body and a hook body arranged on the rod body, which has the following problems: first, the traditional surgical retractor has only one hook head, which cannot meet the needs of opening the surgical incision
The second is that the traditional surgical retractor is manually pulled and kept fixed. During the operation, the operation requirements for medical personnel are relatively strict. sense of pain, therefore, in order to solve such problems, we propose an automatic locking mechanism for clinical operation retractors in general surgery

Embodiment

[0020] Embodiment: When in use, the two splints 14 of the device are placed on the patient's surgical incision, such as the patient's leg, and then the electric telescopic rod 12 is activated to push the cross bar 13 and the splint 14, and the patient is lifted by the splint 14. The position of leg operation incision place is fixed, then rotates turning lever 16, and turning lever 16 drives gear plate 7 to rotate, and gear plate 7 drives two rack plates 4 to move toward opposite direction, and rack plate 4 drives slide block 9 again Sliding in the chute 10, the rack plate 4 drives the connecting plate 5 and the draw hook body 2 to move, and makes the two rack plates 4 slide in the movable holes of the two connecting plates 5 respectively. When the draw hook body 2 moves the patient's surgery When the incision is opened to facilitate the operation and observation of the medical personnel, stop rotating the rotating rod 16, and then insert the fixing rod 6 into a suitable fixing ...

Abstract

The invention belongs to the medical field, and in particular discloses an automatic locking mechanism for clinical operation hooks in general surgery, including a mounting plate, the two ends of the mounting plate are arranged in a semicircular shape, and the middle part is arranged in a rectangular structure, and the installation One side of the top of the plate is rotatably connected to a gear plate, and the top of the gear plate is connected to a rotating rod. The top of the mounting plate is provided with two symmetrically arranged chutes along its length direction, and each chute is slidably connected. There are sliders, the top of each slider is connected with a rack plate, and the lower wall of the rod body at the left end of the rack plate located above is connected with the upper wall of the rod body at the left end of the rack plate located below. There are connection plates. The invention can be fixed on the patient, and the device can effectively open the patient's surgical incision, which is convenient for the doctor to perform surgery and observation. At the same time, the device can fix the retractor to prevent the retractor from falling off and causing physiological damage to the patient again. Suitable for promotion.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an automatic locking mechanism for clinical operation hooks of general surgery. Background technique [0002] When doctors perform clinical operations, in order to facilitate observation of the surgical opening, retractors are often used to open the surgical incision. The traditional surgical retractor is composed of a rod body and a hook body arranged on the rod body, which has the following problems: the first is that the traditional surgical retractor has only one hook head, which cannot meet the needs of opening the surgical incision. The second is that the traditional surgical retractor is manually pulled and kept fixed. During the operation, the operation requirements for medical personnel are relatively strict. sense of pain, therefore, in order to solve such problems, we propose an automatic locking mechanism for clinical operation retractors in general surgery.
