Abstract
The utility model provides a multi -functional ware that shows of pin type combination formula who uses under the peritoneoscope. This apparatus is by handle, pin type action bars and operating head triplex. The operating head divides connecting portion and appears the portion, and connecting portion have connecting hole AND operation rod cover to go into to connect, and the portion of appearing is the rectangular bodily form, cylindrical and hook -type. Directly puncture the pin type action bars during operation and get into the abdominal cavity, with operating head most advanced assembled fitting of AND operation pole after the abdominal cavity is sent into to puncture sheath pipe to push away, dial, push up, draw and show internal organs, blood vessel and lesion tissues. Can lift the operating head off in the abdominal cavity after accomplishing the operation and take out through the sheath pipe, the pin type action bars withdraws from the back and only show a pinhole on the stomach wall.
Description
Technical field:
The present invention relates to a kind of under peritoneoscope for the operating theater instruments that internal organs appear, a kind ofly can appear apparatus the pin type of intraperitoneal charge and discharge operations head is multifunctional assembled.
Background technology:
At present, the conventional instrumentation diameters appeared for internal organs under peritoneoscope is 5mm ~ 15mm, and the sheath pipe that all to need by external diameter be 5.5mm ~ 15.5mm enters abdominal cavity, makes stomach wall leave several cicatrix being about 8mm ~ 24mm." pin type " laparoscopic instrument external diameter reported in recent years is comparatively thin, enters abdominal cavity, also can enter abdominal cavity by Direct perforantes, incision of abdominal wall is shortened, but shortcoming be: (1) operating head jaw is little, grasp the easy slippage of thing by thinner sheath pipe; (2) operating head is too sharp, and have the danger causing visceral organ injury during operation in vivo, (3) action bars inside must establish a push-pull bar that nose plier just can be made to move, and thus action bars external diameter is still comparatively thick, and Post operation still leaves scar on stomach wall.Therefore, this improvement attenuated by operating apparatus simply does not bring the breakthrough of matter to laparoscopic surgery effect." puncture type multifunctional poking rod used under laparoscope " (application number 200910176311.2) that we once designed effectively can make up the deficiency of above " pin type " apparatus, but the shortcoming of this group of excellent operating head is: (1), for cylindric and be only provided with through wires hole and hanging wire groove, function is limited to; (2) connected mode of operating head and action bars only adopts the connection of annular convex rib and annular groove, and when performing the operation, operating head easily rotates.
Summary of the invention:
Large compared with trauma of abdomi napwall that is thick, that cause in order to solve existing celioscope operating apparatus, other operating apparatuss and method poor effect or apply the problems such as limited, the invention provides a kind of can the pin type combination type displaying unit of charge and discharge operations head.This displaying unit comparatively " puncture type multifunctional poking rod used under laparoscope " adds the operating head of cuboid and hook-type exposing portion, make to appear function showed increased, operating head connecting portion with pin type action bars setting up stringer and has been connected convex surface and concave surface, operating head can be avoided when appearing operation to rotate.
Technical solution of the present invention is:
Can the pin type combination type displaying unit of charge and discharge operations head, it is characterized in that: the tip of pin type action bars is connected by being inserted in operating head, and end is fixedly connected with handle bolt.Pin type action bars is done by real core cylinder unoxidizable alloy steel, the long 25 ~ 35cm of diameter 1 ~ 2mm, and one end is needle tip, establishes 1 ~ 2 semi-circular groove and 1 stringer circle to lack concave surface after needle point.Operating head divides connecting portion and exposing portion, connecting portion is column by barium sulfate and plastic material mixed injection molding, diameter 3 ~ 10mm, long 2 ~ 4cm, a stringer connecting hole is established, long 2 ~ 4cm, aperture 1 ~ 2mm in it, 1 ~ 2 semi-circular convex tendon and 1 stringer circle is established to lack convex surface in hole, in the annular groove that can snap in action bars when being connected with action bars and stringer concave surface; Clamp area is established along Y-direction exposing portion direction, long 1cm, dark 1mm in both sides apart from the outside correspondence at connecting hole opening 1cm place.The exposing portion of operating head is cuboid (appearing plate), cylindrical (appearing rod) and hook-type (appearing hook): appear plate or appear excellent and formed by barium sulfate and plastic material mixed injection molding together with connecting portion; Appear edges of boards angle circle blunt, long 3 ~ 8cm, wide 1 ~ 3cm, thick 2 ~ 4mm (Fig. 1); Appear rod long 2 ~ 4cm, diameter 3 ~ 10mm, anterior top is hemispherical, is followed successively by thereafter through wires hole and hanging wire groove (Fig. 2); Appear hook to embed with connecting portion and be connected, be made up (Fig. 4) of the stainless steel silk (Fig. 3) of diameter 1 ~ 2mm and thick 1 ~ 3mm, the corner blunt cuboid corrosion resistant plate of circle respectively, coupler body is different radians, maximum transverse diameter is 5 ~ 15mm, can respectively by the puncture sheath pipe of 5mm, 10mm, 12mm and 15mm.
When laparoscopic surgery operates, action bars puncture is entered abdominal cavity, need dissimilar operating head to send into abdominal cavity through operation sheath pipe according to operation, at intraperitoneal operating head is inserted in the tip of action bars and is connected, then by pushing away, dial, top, tractive directly appears internal organs or pathological tissues, the hanging wire groove appearing rod also can be utilized to entangle the stitching draught line on internal organs or pathological tissues or intend excision internal organs placenta percreta with pin type hook Direct perforantes, carry out flexible operating by handle in vitro to appear, also can utilize and appear the line segment that excellent through wires hole carries and carry out organizing ligation under another apparatus is assisted.Operation terminates rear handling tongs and is separated with action bars by operating head, and takes out through other sheath pipes.
The invention has the beneficial effects as follows, handling tongs and corresponding puncture sheath pipe thereof can be replaced in laparoscopic surgery, thus reduce stomach wall operative scar, reach Wicresoft and surgical effect attractive in appearance more.
