The utility model relates to a kind of puncture outfits for being easily inserted control, including sheath assembly and the piercing assembly for being interspersed in sheath assembly, the puncture needle of piercing assembly stretches out outside the casing of sheath assembly, the sleeve outer wall is equipped with forward screw thread, at least provided with one of reverse thread after forward screw thread, positive lead ring is equipped between forward screw thread rear end and reverse thread front end, reverse thread rear end has reversed baffle ring, the positive lead ring and reversed baffle ring are round table-like, wherein the conical side surface direction of positive lead ring punctures direction, the conical side surface of reversed baffle ring punctures direction backwards.Puncture outfit casing tube surface screw thread is used forward and reverse design by the utility model, forward screw thread section is conducive to puncture smooth insertion, reverse thread Duan Zeke makes Cat-in resisting force become larger, it is therefore prevented that paracentesis depth is not easy to control and be inserted into and too deep injure interior tissue in doctor's use process.
Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of puncture outfit for being easily inserted control.
Background technique
In laparoscopic surgery, doctor generallys use puncture outfit and punctures abdominal cavity, to intraperitoneal conveying gas, and establishes endoscope
The channel in abdominal cavity is passed in and out from the external world with surgical instrument.In puncture outfit puncture process, when the mouth that puncture needle is opened by skin surface
When son penetrates tissue, the casing of puncture outfit also penetrates in tissue therewith, and the cannula structure of existing puncture outfit is unfavorable for curing
Raw grasp paracentesis depth brings adverse effect to conditions of patients so that causing to penetrate too deep and injure inside of human body tissue.
Summary of the invention
Technical problem to be solved by the utility model is: the utility model provides in order to overcome the deficiencies in the existing technology
A kind of puncture outfit being easily inserted control.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of puncture outfit for being easily inserted control,
Including sheath assembly and the piercing assembly for being interspersed in sheath assembly, the puncture needle of piercing assembly stretches out outside the casing of sheath assembly,
The sleeve outer wall is equipped with forward screw thread, at least provided with one of reverse thread after forward screw thread, forward screw thread rear end and anti-
To positive lead ring is equipped between flighting front end, reverse thread rear end has reversed baffle ring, the positive lead ring and reversed baffle ring
It is round table-like, wherein the conical side surface of positive lead ring punctures direction towards direction, the conical side surface of reversed baffle ring is punctured backwards.
Further, twice reverse thread is equipped with after the forward screw thread, per pass reverse thread rear end all has reversely
Baffle ring, to facilitate doctor preferably to control paracentesis depth when operating.
The conical side surface of the positive lead ring and reversed baffle ring with respective big end top surface arc transition, to prevent from wearing
To the damage of tissue when thorn.
The beneficial effects of the utility model are: puncture outfit casing tube surface screw thread is used forward and reverse design by the utility model,
Forward screw thread section is conducive to puncture smooth insertion, and reverse thread Duan Zeke makes Cat-in resisting force become larger, it is therefore prevented that doctor's use process
Middle paracentesis depth is not easy to control and is inserted into and too deep injures interior tissue.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1. sheath assembly, 2. piercing assembly 2-1 puncture needle, 3. casing 3-1. forward screw thread 3-2. reverse thread
The reversed baffle ring of 3-3. forward direction lead ring 3-4.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
A kind of puncture outfit being easily inserted control as shown in Figure 1 including sheath assembly 1 and is interspersed in sheath assembly 1
The puncture needle 2-1 of piercing assembly 2, piercing assembly 2 stretches out outside the casing 3 of sheath assembly 1, and 3 front end face of casing is oblique
Cutting plane.
It is equipped with forward screw thread 3-1 in the middle part of 3 outer wall of casing, is equipped with two reverse thread 3-2 after forward screw thread 3-1,
The forward direction rear end lead ring 3-3, per pass reverse thread 3-2 is equipped between the rear end forward screw thread 3-1 and the preceding front end the 3-2 of reverse thread together
Reversed baffle ring 3-4 is all had, the positive lead ring 3-3 and reversed baffle ring 3-4 are round table-like, wherein forming positive lead ring 3-
3 rotary table small end is preceding, and big end is rear, so that the conical side surface of positive lead ring 3-3 is inserted when being conducive to puncture towards direction is punctured
Enter；And forming the rotary table big end of reversed baffle ring 3-4 preceding, small end is rear, so that the conical side surface of reversed baffle ring 3-4 is backwards to puncturing
Direction generates resistance when puncturing in place and controls paracentesis depth convenient for doctor.
The conical side surface of the positive lead ring 3-3 and reversed baffle ring 3-4 with respective big end top surface arc transition, this
Damage when sample can prevent from puncturing to tissue.
Puncture outfit casing tube surface screw thread is used forward and reverse design by the utility model, and 3-1 sections of forward screw thread are conducive to puncture
Smooth insertion, reverse thread 3-2 Duan Zeke make Cat-in resisting force become larger, it is therefore prevented that paracentesis depth is not easy to control in doctor's use process
And it is inserted into and too deep injures interior tissue.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
It is not limited to the contents of the specification with novel technical scope, it is necessary to its technology is determined according to scope of the claims
Property range.
