Abstract
The utility model is related to a kind of medical straight type liver cancer and portal vein cancer and takes bolt to clamp, the stage casing of two tong arms is connected with the mutual riveted of rivet rotating shaft, binding clip is arranged on tong arm front end, binding clip is linearly connected with tong arm, binding clip has the flat arc-shaped concave structure of preceding flat rear wide gradual change type, binding clip madial wall is wave camber cone structure, when gripping cancer embolus, two binding clip madial wall wave camber cone structures are tightly engaged, when two tong arms drive two binding clip closures, the flat arc-shaped concave structure pairing of preceding flat rear wide gradual change type of two binding clip head ends, formation sealedly takes bolt chamber.The binding clip of the flat arc-shaped concave of gradual change type of dehiscing of the present utility model, TTPV can be effectively gripped, binding clip dehisces to accomplish to maximize when blood vessel is stretched into binding clip part, makes single gripping amount big, after binding clip closure, the binding clip side wall conical surface is tightly engaged, and cancer embolus is difficult for drop-off after binding clip closure, will not pollute the surface of a wound, it ensure that the radical-ability of TTPV embolectomy, it is easy to operate, shorten operating time, improve efficiency.
Description
Technical field
It is used for the clamp for taking out cancer embolus or thrombus in portal vein in the utility model and a kind of liver surgery, especially
TTPV takes bolt clamp in a kind of operation for liver cancer and portal vein cancer.
Background technology
Liver neoplasm develops into middle and advanced stage, often have tumor embolus invade liver Major Vessels, such as portal vein, vena hepatica,
Can cancer embolus take in blood vessel directly affects patient's tumor recurrence morning and evening and life span only.It clinically there is no special blood vessel at present
Cancer embolus takes bolt to clamp, used take bolt apparatus to be replaced using the existing apparatus such as Lithotomy forceps or tweezers mostly.This kind of pliers exists
There is many weak points in surgical procedure：Pliers head is generally arc-shaped structure, when it takes bolt in reeve blood vessel after opening,
Circular arc head opening dimension is small, causes the crawl amount of a cancer embolus less, pushes, makes toward internal blood vessel while being also possible to a cancer embolus
Into bolt difficulty, and TTPV is taken, quality is relatively soft, and most of cancer embolus has more or less adhesion with portal vein tube wall
（See Fig. 1）, or even there are tiny blood vessels to be connected, therefore only take thing clamp to hold with clinically of different shapes at present when taking bolt
Cancer embolus, the strength too conference crushing cancer embolus of folder, causes tumour spread；Strength is too small and effectively can not take out cancer embolus, and
During cancer embolus taking-up, a series of problems, such as due to operating force, cancer embolus is likely to occur slight drippage, easily causes last swollen
Tumor metastasis, influences surgical effect.
The content of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency in the presence of prior art, and provides one
Utility function protrusion, reasonable in design are planted, the medical straight type liver cancer portal vein cancer of TTPV can be easily and effectively gripped
Bolt takes bolt to clamp.
The utility model solves the technical scheme that is used of above-mentioned technical problem：A kind of medical straight type liver cancer portal vein cancer
Bolt takes bolt to clamp, including binding clip, tong arm, rivet rotating shaft, spacing sawtooth, handle, and the stage casing of two tong arms is with the mutual riveting of rivet rotating shaft
Connection is closed, the binding clip is arranged on tong arm front end, and binding clip is linearly connected with tong arm, binding clip has preceding flat rear wide gradual change type
Flat arc-shaped concave structure, binding clip madial wall is wave camber cone structure, when gripping cancer embolus, two binding clip madial wall wave arcs
Type cone structure is tightly engaged, when two tong arms drive two binding clip closures, and the preceding flat rear wide gradual change type of two binding clip head ends is put down
Arc-shaped concave structure pairing, formation sealedly takes bolt chamber.
The material for taking bolt to clamp is the medical stainless steel or medical plastic for meeting biocompatibility requirement.
Head end height after described two binding clip engagements is between 2-6mm, and length is in 10-30mm, and c is in 6- for tail end height
Between 12mm, width is between 6-12mm.
The utility model compared with prior art, has an advantageous effect in that：Utility function is protruded, the flat arc of gradual change type of dehiscing
The binding clip of shape concave surface, can effectively grip TTPV, and when blood vessel is stretched into binding clip part, binding clip dehisces to accomplish to maximize, and makes
Single gripping amount is big, and cancer embolus is difficult for drop-off after binding clip closure.The utility model processing and manufacturing is easy, with low cost, more suits liver
It is the need for dirty surgical clinical treatment and easy to operate, it is practical, with preferable market prospects.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings
As shown in figure 1, medical straight type liver cancer and portal vein cancer of the present utility model takes bolt to clamp, including binding clip 1, tong arm 2, riveting
Follow closely rotating shaft 3, spacing sawtooth 4 and handle 5.The leading portion of tong arm 2 for connecting binding clip 1 is linearly, and the stage casing of two sections of tong arms 2 is turned with rivet
The mutual riveted of axle 3 is connected；When two tong arms 2 drive the closure of binding clip 1, the flat arc-shaped concave pairing of preceding flat rear wide gradual change type of head end,
Formation sealedly takes bolt chamber 6.When gripping cancer embolus, the cone structure of two madial wall wave cambers 7 of binding clip 1 is tightly engaged.
Such as Fig. 2, shown in 3, head end height a is between 2-6mm after two binding clip engagements, and length b is between 10-30mm, tail
Hold height c between 6-12mm, width d is between 6-12mm.
As shown in figure 4, during upper and lower binding clip engagement, the close note of two conical surface 8 is closed, and enhances the sealing property after binding clip engagement,
Prevent that cancer embolus comes off in art.
As shown in figure 5, using suitably taking bolt to clamp, pressing close to flat camber binding clip cambered surface according to vein blood vessel size in art
Vascular wall 9 stretch into it is intravascular, due to it is preceding it is flat after wide formula binding clip head end height a sizes it is smaller, be not in that intravascular cancer embolus is past
In the phenomenon that extrudes, now binding clip dehisce size h maximizations, can the smooth the maximum amount of thrombus of single gripping.
Embodiment：
The utility model is cutting off right liver tumour in operation in use, by taking right liver tumour right branch of portal vein cancer embolus as an example
Afterwards, right branch portal vein is opened, first by binding clip head end height 6mm, binding clip length 30mm, binding clip tail end height 12mm, binding clip
Height 12mm cancer embolus pincers, take bolt pincers to first pass through handle 5 and rivet rotating shaft 3 by the opened with certain angle of binding clip 1 with suitable in portal vein
The size of blood vessel is answered, the binding clip opened is stretched into intravascular, then blood vessel mouthful cancer embolus is extracted after binding clip 1 is closed out, exhausts venous blood
The larger cancer embolus of the mouth of pipe.After the completion of blood vessel mouthful cancer embolus is exhausted, the characteristics of according to vena portae hepatica vessel branch from the coarse to fine, pincers are reused
Head end height 4mm, binding clip length 20mm, binding clip tail end height 8mm, binding clip width 8mm cancer embolus pincers, take out in vein blood vessel
Hold cancer embolus, finally using binding clip head end height 2mm, binding clip length 10mm, binding clip tail end height 6mm, binding clip height 6mm cancer embolus
Pincers, exhaust portal vein end and most carefully locate cancer embolus.
