Problems solved by technology

[0004] The overall structure is thick and bulky, and the semi-circular elastic arm will greatly increase the size of the skull opening and the working length of the outer cannula, reduce the operation space, and make the internal operation inflexible. At the same time, the position, shape and size of the opening Different, different requirements for the elastic arm, not feasible; and increase the trauma and cost of the patient;
[0005] The soft tissue expanders disclosed in other relevant patents all have the disadvantages of complex structure, large trauma to the patient, and poor technical implementation.

Abstract

The invention discloses a soft tissue expander, which comprises an outer sleeve and an inner sleeve. The inner sleeve is hollow to form a first through hole and a second through hole with different axes, the outer surface and the head of the inner sleeve are conical, and a clamping groove is formed in the tail of the inner sleeve; the outer sleeve is hollow, the inner surface and the outer surfaceof the outer sleeve are conical surfaces, the inner surface of the outer sleeve is matched with the outer surface of the inner sleeve, and a clamping part is arranged at the rear part of the outer sleeve; and when the inner sleeve reaches the set position of the outer sleeve, the clamping part of the outer sleeve can be clamped into the clamping groove of the inner sleeve by rotating the outer sleeve, so that the relative fixation of the positions of the inner sleeve and the outer sleeve is realized.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a soft tissue expander. Background technique [0002] In neurosurgery, in order to reduce surgical trauma and minimize patient pain, endoscopes are used. During surgery, only a small hole is opened in the skull, and then the endoscope is introduced into the cranial cavity through a soft tissue dilator. To perform surgery, the use of endoscope reduces the risk of surgery caused by large-scale craniotomy, and also reduces the pain of patients. [0003] In patent 201210066281.1, an endoscopic introduction device is disclosed. When in use, the inner tube and the outer tube are inserted into the patient's cranial cavity from the surgical incision on the patient's head. After reaching a predetermined depth, the outer tube is fixed, and the After the inner tube is taken out, the endoscope or other surgical instruments can be introduced through the outer tube for surgery, but the device has the ...
