Abstract
The utility model discloses a kind of perforator for adiposis patient laparoscopic surgery, comprise puncture tube, support channels body and thimble assembly, in support channels body, be provided with support channels, one end at puncture tube is provided with spacing collar, puncture tube and described support channels are connected to one, in support channels, be provided with sealing ring, be provided with a flushing valve at the outer surface of support channels body, flushing valve is communicated with the support channels in support channels body, in support channels, be set with puncture needle, thimble assembly comprises a socket bar, socket bar comprises stage casing flexible pipe and lays respectively at far-end hard tube and the near-end hard tube at flexible pipe two ends, described stage casing.This utility model can be because the position of socket bar is adjusted and damaged tissue, simultaneously owing to being provided with the circular protrusion that increases frictional force on flexible pipe, when operation, can not move to operator's direction owing to having increased frictional force between tissue and socket bar, be conducive to the carrying out of operation, increased the safety of operation.
Description
Technical field
This utility model relates to a kind of perforator, relates in particular to a kind of perforator for adiposis patient laparoscopic surgery.
Background technology
In human body in peritoneoscope medical operating, once finding focus in body just need to perform the operation its excision, in operation process, tend to use perforator, perforator generally includes as the sleeve assembly of other operating theater instruments admission passages with through the puncturing lever in sleeve assembly.For transdermal, first cut epiderm skin with scalpel, then puncturing lever transdermal enter body cavity.Exert pressure by the near-end to described puncturing lever, promote the tip of described puncturing lever through skin, until it enters body cavity.Perforator enters body cavity, extracts puncturing lever out, and sleeve assembly just can be used as the mis instruments passage of carrying out endo-surgical and splanchnoscopy operation.
Utility model content
The purpose of this utility model is to provide a kind of perforator for adiposis patient laparoscopic surgery, solves the shortcoming that prior art exists.
This utility model adopts following technical scheme to realize:
A kind of perforator for adiposis patient laparoscopic surgery, comprise puncture tube, support channels body and thimble assembly, in described support channels body, be provided with support channels, one end at described puncture tube is provided with spacing collar, puncture tube and described support channels are connected to one, in support channels, be provided with sealing ring, be provided with a flushing valve at the outer surface of described support channels body, described flushing valve is communicated with the support channels in support channels body, in support channels, be set with puncture needle, it is characterized in that, described thimble assembly comprises a socket bar, described socket bar comprises stage casing flexible pipe and lays respectively at far-end hard tube and the near-end hard tube at flexible pipe two ends, described stage casing.
Further, the outer surface of described stage casing flexible pipe is coaxially arranged with the projection of ring-type.
Useful technique effect of the present utility model is: the position that can adjust unavoidably socket bar when operation is carried out, this utility model can be because the position of socket bar is adjusted and damaged tissue, simultaneously owing to being provided with the circular protrusion that increases frictional force on flexible pipe, when operation, can not move to operator's direction owing to having increased frictional force between tissue and socket bar, be conducive to the carrying out of operation, increased the safety of operation.

Fig. 3 is the structure chart of socket bar.
Fig. 4 is the structure chart of stage casing flexible pipe.
Detailed description of the invention
By the description to embodiment below; to more contribute to public understanding this utility model; but specific embodiment given applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
The perforator for adiposis patient laparoscopic surgery as shown in Figures 1 to 4, comprise puncture tube, support channels body 3 and thimble assembly, in support channels body 3, be provided with support channels, be provided with spacing collar 2 in one end of puncture tube 1, one end and the support channels of puncture tube are connected to one, in support channels, be arranged on sealing ring, be provided with a flushing valve 4 at the outer surface of support channels body, flushing valve 4 is communicated with the support channels in support channels body, in support channels, be set with puncture needle, thimble assembly comprises a socket bar 5, socket bar 5 comprises stage casing flexible pipe 6 and lays respectively at far-end hard tube and the near-end hard tube at flexible pipe two ends, described stage casing, the outer surface of stage casing flexible pipe 6 is coaxially arranged with the projection 7 of ring-type.In another embodiment, the outer surface of stage casing flexible pipe 6 is provided with screw-like projection, and the state of screw-like projection is not as good as circular protrusion, but manufacturing cost is relatively cheap.While using this utility model operation, can be because the position of socket bar 5 is adjusted and damaged tissue, simultaneously owing to being provided with the circular protrusion that increases frictional force on the flexible pipe of stage casing, when operation, can not move to operator's direction owing to having increased frictional force between tissue and socket bar, be conducive to the carrying out of operation, increased the safety of operation.
Certainly; this utility model can also have other various embodiments; in the situation that not deviating from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to this utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of this utility model.
