This utility model discloses a multi-angle gingival scalpel, relating to the field of scalpel technology. It includes a handle, a base, a blade, and an angle adjustment mechanism. One end of the handle is connected to the base via the angle adjustment mechanism, and the blade is detachably mounted on the base. The angle adjustment mechanism includes a knob, a limiting block, a limiting plate, a ball, an elastic element, and a connecting rod. The angle adjustment mechanism allows for flexible adjustment of the base angle, which in turn adjusts the blade angle. This enables the surgeon to precisely position and operate the blade according to the patient's oral condition, ensuring that cutting and trimming operations are accurately applied to the target gingival tissue. This improves surgical precision and reduces surgical errors caused by operational deviations.

The utility model relates to the technical field of auxiliary positioning devices, in particular to an anorectal surgery auxiliary positioning device which comprises a base, a first adjusting piece is arranged at the top of the base and comprises a U-shaped fixing plate, a rectangular vertical pipe is arranged at the top of the U-shaped fixing plate, and a rectangular supporting rod capable of being adjusted up and down is arranged in the rectangular vertical pipe. A second adjusting part is arranged on the rectangular supporting rod and comprises a cross rod, a connecting ring is arranged at the bottom of the cross rod and close to the left side, the connecting ring is connected with a connecting belt, and a detachable sticky patch is arranged on the connecting belt. According to the auxiliary positioning device for the anorectal surgical operation, through cooperation of the first adjusting piece and the second adjusting piece, accurate adjustment of the position of the viscous patch is achieved, medical staff can easily adjust the height and the position of the viscous patch through the controller and the fine adjustment piece, and therefore the requirements of different patients and operations are met; by means of the design, the problem that the elastic band is not easy to control is solved, and operation flexibility and fineness are improved.

The utility model relates to a kind of high blood pressure cerebral hemorrhage minimally invasive puncture drainage operation positioning auxiliary device, including base and sliding block, the base is 180 ° fan ring plate, its surface is equipped with sliding slot, and its both ends are equipped with positioning bolt respectively;The sliding slot is circular-arc groove, and with the base concentric, its central angle is greater than 120 °;The positioning bolt is set along the radial direction of the base, can be tightly in the left and right temple of patient's head;The sliding block is fan ring plate, its shape and size are adapted to the sliding slot, and be placed in the sliding slot movably, and can move along concentric circle of the sliding slot;Still including limiting structure, install on the sliding block, with the linear type puncture channel of the center of base pointing to straight line type.This utility model is by hand operation and is connected on patient's head with base, then by moving sliding block and will puncture channel aim at skull hole, it can be realized puncture positioning, improve the efficiency and accuracy of positioning operation, create favorable conditions for improving operation quality.

The invention discloses a jaw 90-degree corner mechanism and an electric anastomat, and the jaw 90-degree corner mechanism comprises a steering assembly which comprises a steering pull rod; the steering control assembly comprises a fixedly arranged steering fixing base, a steering control base rotationally connected with the far end of the steering fixing base and a cutting knife steering base connected with the steering fixing base and the steering control base so that a cutting knife can penetrate through the cutting knife steering base, and a plurality of limiting grooves formed in the steering control base in a 90-degree arc length mode are formed in the steering control base; a steering locking block matched with the limiting groove is arranged on the steering fixing seat, the far end of the cutting knife steering seat is rotationally connected with the steering control seat, a steering adjusting groove matched with the near end of the cutting knife steering seat is formed in the steering fixing seat, a driving shaft is arranged on the steering control seat, and a steering driving groove matched with the driving shaft is formed in the far end of the steering pull rod. According to the jaw 90-degree rotation angle mechanism and the electric anastomat, 90-degree rotation angle of the jaw can be achieved, and operation is convenient and fast.
