Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention aims to provide a trocar shell, which solves the problem that the locking mechanism between the two trocar shell parts in the prior art is prone to unnecessary shaking or movement inside the trocar shell, which affects the locking mechanism. The normal work of the mechanism, at the same time, the existing rotary locking mechanism may be stuck

Embodiment Construction

[0039] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. Axial means a direction along the central axis or along a direction parallel to the central axis.

[0040] The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0041] see figure 1 and figure 2 , the present embodiment provides a trocar housing, including a locking mechanism 30 and a first housing part and a second housing part selectively connected by the locking mechanism 30 . The l...

Abstract

The invention discloses a puncture device shell and a puncture device. The puncture device shell comprises a first shell component, a second shell component and a locking mechanism for selectively connecting the first shell component with the second shell component, and the locking mechanism comprises a locking part and a matching part; the locking part comprises a fixing column and a rotary arm;the fixing column is rotatably arranged on the second shell component and arranged on the rotary arm; the matching part comprises a convex block arranged on the lower end face of the first shell component; and the rotary arm is pivoted through the fixing column to be in clamped fit with or disengaged from the convex block, and the first shell component and the second shell component are selectively connected. The puncture device comprises the puncture device shell. The locking mechanism in the puncture device shell does not shake and move unnecessarily, the locking mechanism is pressed to realize clamped fit and disengaging between the two puncture device shell components, and thus the defect that a rotary locking mechanism is prone to being stuck is avoided.

Description

technical field [0001] The invention relates to a casing device, in particular to a puncture device casing and a puncture device, belonging to the field of medical equipment. Background technique [0002] A trocar is a surgical instrument used to create a passage into the abdominal cavity. A trocar usually includes two parts, a sleeve assembly and a puncture mandrel. Its general clinical use method is: first cut a small incision in the abdomen of the patient, then pass the distal end of the puncture mandrel through the sleeve assembly, and expose the distal end of the puncture mandrel from the distal end of the sleeve assembly. The doctor holds the proximal end of the puncture mandrel, and applies puncture operation force to the trocar, so that the distal end of the puncture mandrel is inserted into the abdominal cavity and drives the distal end of the cannula assembly into the abdominal cavity, and the puncture mandrel is pulled out, and the cannula The assembly forms a p...
