Embodiment 1

[0027] refer to Figure 1-4 , a skull base repair device for minimally invasive transsphenoidal pituitary adenoma surgery, comprising a circular guide rail 1 and a bracket arranged in the middle of the circular guide rail 1, and also includes a circular drive device, a radial adjustment device, an elastic leak-proof device and feeding device;

[0028] The radial adjustment device includes a rotating horizontal plate 23 movable along the radial direction of the annular guide rail 1. The inner rotation of the rotating horizontal plate 23 is connected with a screw rod 24, and the screw rod 24 is connected with an adjusting plate 25 stuck in the rotating horizontal plate 23. 25. As the screw rod 24 rotates, the elastic leak-proof device moves linearly to and fro, and the elastic leak-proof device includes a skull support plate 3 arranged on the top of the adjustment plate 25;

[0029] The skull support plate 3 is provided with an injection chamber 31 and an extrusion chamber 32. ...

Embodiment 2

[0034] An adjustment handle is also provided on the outside of one side of the rotating horizontal plate 23, and the adjustment handle is fixedly connected with one end of the screw rod 24. The adjustment handle can be manually rotated to drive the screw rod 24 to rotate, and then the adjustment plate 25 is driven to move under the rotational power of the screw thread to realize adjustment. The purpose of different positions of the skull support plate 3 is not only to save cost, but also to facilitate rapid repair of different positions of the skull and reduce the difficulty of surgery.

Abstract

The invention discloses a skull-base repairing device for a transsphenoidal-pituitary-adenoma minimally invasive surgery. The skull-base repairing device comprises an annular guiding rail and a support arranged in the middle of the annular guiding rail, and also comprises a circumference driving device, a radial-direction adjusting device, an elastic leakage-proof device and a feeding device; theradial-direction adjusting device comprises a rotatable transverse plate moving in the radius direction of the annular guiding rail, a threaded rod is rotationally connected inside the rotatable transverse plate, and an adjusting plate clamped inside the rotatable transverse plate is connected on the threaded rod, and drives the elastic leakage-proof device to straightly reciprocate along with rotating of the threaded rod; the elastic leakage-proof device comprises a skull supporting plate arranged at the top of the adjusting plate, a liquid injection cavity and an extruding cavity are formedin the skull supporting plate, an arc pressing plate is arranged inside the extruding cavity, and air sacs are arranged on the two edges of one side of the arc pressing plate. The skull-base repairingdevice for the transsphenoidal-pituitary-adenoma minimally invasive surgery is reasonable in design, a repairing position can be multi-directionally and rapidly adjusted, the surgery difficulty is reduced, dual sealing is achieved and fits a skull wound, repairing liquid is prevented from leaking outwards, and the quality of the transcranial surgery is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a skull base repair device for minimally invasive surgery of transsphenoidal pituitary adenoma. Background technique [0002] Over the past 20 years, the popularity of transsphenoidal pituitary tumor resection has gradually reduced the proportion of transcranial surgery. However, due to the different growth and expansion directions of pituitary tumors, these two approaches are difficult to replace each other and each has its own advantages. the value of existence. According to Guiot's (1973) report, among the 563 cases of pituitary tumors he operated on personally, only 28% of the patients were absolutely suitable for the transsphenoidal approach, 10.5% were definitely suitable for the transcranial approach, and the remaining 61.5% of the patients were treated with the above two methods. Any one of these approaches can achieve satisfactory therapeutic effect. However,...
