Problems solved by technology

[0002] At present, the scalp incision and muscle separation in head surgery are separated by claw or hook traction, but the thin scalp of children and the physiological structure of the posterior cranial fossa lead to the unstable fixation of the existing posterior cranial fossa retractor during the operation. It is easy to disengage, which brings inconvenience and trouble to the operation, and increases tissue damage

Abstract

The invention relates to the technical field of medicinal instruments, in particular to a forceps-type occiput spreader for infants. The forceps-type occiput spreader for infants is characterized in that: a left half forceps and a right half forceps are connected into a forceps body (1) through a hinge pin (2); the front part of the forceps body (1) is a forceps arm (3); the bottom surface of the middle part of the forceps arm (3) is arc-shaped; the middle of the middle part of the forceps arm (3) is provided with a crank arm mechanism (7); the front end of the forceps arm (3) is provided with a spreading claw (4), and the rear part of the forceps arm (3) is provided with a forceps handle (5); and the forceps handle (5) is provided with a locking mechanism (6). The forceps-type occiput spreader for infants has the characteristics of simple structure, convenient use, suitability for the physiological structures of infant scalp and posterior fossa and capabilities of greatly enhancing the fixing stability of the spreader, expanding surgical field and reducing injury to scalp tissues.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a forceps type posterior cranial fossa retractor for children. Background technique: [0002] At present, the scalp incision and muscle separation in head surgery are separated by claw or hook traction, but the thin scalp of children and the physiological structure of the posterior cranial fossa lead to the unstable fixation of the existing posterior cranial fossa retractor during the operation. It is easy to disengage, which brings inconvenience and trouble to the operation, and increases tissue damage. Invention content: [0003] In order to overcome the deficiencies in the prior art, the invention provides a child's forceps type posterior cranial fossa retractor. [0004] The technical scheme adopted by the present invention to solve the technical problem is a kind of pliers-type posterior cranial fossa retractor for children. The right half pliers and the left ...
