Abstract

The utility model a laparoscope which does not need to be take out for wiping and washing when a scene is polluted in an operation, can keep the consecutive uninterrupted operation, which is beneficial to save the operation time, reduce troubles and ensure the operation quality, including a drawtube(3) as well as an objective lens(1) provided at the front end and an ocular(5) provide at the back end, the tube wall of the drawtube(3) is entrained with a splashing tube(2) whose front end is provided with an outlet corresponding to the objective lens(1), the back end or the splashing tube(2) backward bends and inclines for offsetting from the drawtube(3), the back end of the splashing tube has an entrance end(21), the splashing tube provides an opening and closing switch(4) at an internally extending position at the entrance end(21). The utility model provides an improved laparoscope, which can wash the objective lens inside the abdominal cavity and keep the clear view sight of the operation.

Description

A kind of peritoneoscope

Technical field

This utility model relates to endoscope, particularly peritoneoscope.

Background technology

When adopting peritoneoscope to implement operation, because its composition lens is built in the abdominal cavity, so when exposing surgical field of view, composition lens is infected with by water smoke, bloodstain etc. easily, it is unclear that surgical field of view is shown.At this moment need peritoneoscope taken out in the sheath composition lens is cleaned, operation is interrupted, the operation that can not link up, and because of there is the temperature difference outward in intraperitoneal, peritoneoscope is put into once more behind the intracavity and is stained with knot water smoke easily on the composition lens.The peritoneoscope repeated multiple times is cleaned, and brings inconvenience and trouble to operation.

Summary of the invention

This utility model will solve endoscope objective lens head in abdominal cavity in the operation and is infected with easily and need to take out the problem of cleaning and bringing many troubles and inconvenience to operation, a kind of peritoneoscope of the present utility model is provided for this reason, and this peritoneoscope can clean and need not take out to clean when composition lens is infected with at intracavity.

For addressing the above problem, the technical solution adopted in the utility model comprises lens barrel and the set set ocular head of composition lens and rear end of front end thereof, its special character is attached on the lens barrel barrel syringe pipe to be arranged, the syringe pipe front end is provided with outlet corresponding to composition lens, the oblique lens barrel that departs from of syringe pipe rearward end lateral bending, this rearward end of syringe pipe has arrival end, and syringe pipe Yan Chu in arrival end is provided with open-close on-off.

Described syringe pipe so design is suitable: this syringe pipe has the circular arc outer wall and lens barrel outer wall kiss connects, forming the transverse section between circular arc outer wall and the lens barrel barrel that surrounded by the circular arc outer wall is half moon-shaped tube chamber, be that the syringe pipe tube chamber is surrounded by its circular arc outer wall and lens barrel barrel, from cross section, this circular arc outer wall is equivalent to the bigger cylindrical of diameter, and syringe pipe is equivalent to the less interior circle of diameter and is inscribed within this cylindrical.

Syringe pipe is attached to the lens barrel outer wall, and from cross section, the maximum external drum direction of the relative lens barrel of syringe pipe, this direction are positioned at the offside of the optical fiber junction of lens barrel on circumferentially, be only.

Syringe pipe forms above-mentioned crescent tube chamber, its oblique this syringe pipe rear portion of leaving lens barrel, and gradual change becomes circle.

The arrival end at syringe pipe rear portion, can be connected with device such as external syringe and can inject cleanout fluid in syringe pipe, this cleanout fluid is aimed at laparoscopically composition lens flushing from the ejection of syringe pipe front end exit, the water smoke be infected with on the composition lens, bloodstain etc. are cleaned up, keep surgical field of view clear.The open-close on-off at syringe pipe rear portion is opened when introducing flushing liquor, and the flushing back opens and closes, and prevents that intraperitoneal from keeping the gas of air pressure and discharging from syringe pipe.

This utility model has its front end of a syringe pipe to be provided with outlet corresponding to composition lens owing to attached on the lens barrel barrel, this rearward end of syringe pipe has arrival end, so this utility model is when composition lens is stain in operation, only need from syringe pipe rear end introducing cleanout fluid, from the front end ejection composition lens is cleaned, keep surgical field of view clear, need not to take out peritoneoscope and clean composition lens, thereby it is uninterrupted to keep operation to link up, and eliminates because of taking out the many troubles and inconvenience that peritoneoscope produces repeatedly.This utility model also helps the saving operating time, reduces patient's misery in the operation, guarantees the operation quality.

The specific embodiment

A kind of peritoneoscope of present embodiment, comprise the ocular head 5 that lens barrel 3 and front end thereof set composition lens 1 and rear end are set, attached on lens barrel 3 barrels have a syringe pipe 2, syringe pipe 2 front ends are provided with outlet corresponding to composition lens 1, the oblique lens barrel 3 that departs from of syringe pipe 2 rearward end lateral bendings, this rearward end of syringe pipe has arrival end 21, and syringe pipe Yan Chu in arrival end 21 is provided with open-close on-off 4; Syringe pipe 2 has circular arc outer wall 22 and connects with lens barrel 3 outer walls kiss, and forming the transverse section between circular arc outer wall 22 and lens barrel 3 barrels that surrounded by circular arc outer wall 22 is half moon-shaped tube chamber 23; Diametrically, syringe pipe 2 relative lens barrel 3 maximum external drum directions, this direction are positioned at the offside of the optical fiber junction 6 of lens barrel on circumferentially.

Claims

1, a kind of peritoneoscope, comprise the set ocular head (5) of composition lens (1) and rear end that lens barrel (3) and front end thereof are set, it is characterized in that attached on lens barrel (3) barrel a syringe pipe (2) being arranged, syringe pipe (2) front end is provided with outlet corresponding to composition lens (1), the oblique lens barrel (3) that departs from of syringe pipe (2) rearward end lateral bending, this rearward end of syringe pipe has arrival end (21), and syringe pipe Yan Chu in arrival end (21) is provided with open-close on-off (4).

2, peritoneoscope as claimed in claim 1, it is characterized in that syringe pipe (2) has circular arc outer wall (22) and lens barrel (3) outer wall kiss and connects, forming the transverse section between circular arc outer wall (22) and lens barrel (3) barrel that surrounded by circular arc outer wall (22) is half moon-shaped tube chamber (23).
