Problems solved by technology

[0002] At present, the separation of the scalp and muscles in head surgery is separated by claws or hooks, but the scalp is thin in children, which causes the existing mastoid retractor to be easily disengaged during the operation because of its unreliable fixation. Inconvenient and cumbersome, with increased tissue damage

Abstract

The invention relates to the technical field of medicinal instruments, in particular to a forceps-type mastoid retractor for infants. The forceps-type mastoid retractor 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 middle part of the forceps arm (3) is arc-shaped; the front end of the forceps arm (3) is provided with a retracting 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 mastoid retractor for infants has the characteristics of simple structure, convenient use, suitability for the physiological structure of infant scalp and capabilities of greatly enhancing the fixing stability of the retractor, avoiding disturbing surgical field and reducing injury to scalp tissues.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clamp-type mastoid retractor for children. Background technique: [0002] At present, the separation of the scalp and muscles in head surgery is separated by claws or hooks, but the scalp is thin in children, which causes the existing mastoid retractor to be easily disengaged during the operation because of its unreliable fixation. Inconvenient and troublesome, and increased tissue damage. Invention content: [0003] In order to overcome the deficiencies in the prior art, the invention provides a clamp-type mastoid retractor for children. [0004] The technical solution adopted by the present invention to solve the technical problem is a clamp type mastoid retractor for children. The right half clamp and the left half clamp are connected by hinge pins to form a clamp body. The front part of the clamp body is the clamp arm, and the middle part of the clamp arm is It ...
