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
The distribution of branch of portal vein medium vessels takes the pincers that bolt is operated in about 90 ° of cancer embolus in a kind of operation for liver cancer and portal vein cancer
Folder.
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 taking bolt difficult.Especially branch of portal vein blood vessel, its blood vessel takes out such cancer embolus particularly difficult in 90 ° of angular displacements.And door
Venous cancerous embolus, quality is relatively soft, and most of cancer embolus has more or less adhesion with portal vein tube wall（See Fig. 1）, or even have
Tiny blood vessels are connected, therefore only take thing clamp to hold cancer embolus, the strength of folder with clinically of different shapes at present when taking bolt
Too conference crushing cancer embolus, causes tumour spread；Strength is too small and effectively can not take out cancer embolus, and takes out process in cancer embolus
In, a series of problems, such as due to operating force, cancer embolus is likely to occur slight drippage, easily causes metastases, influence operation effect
Really.
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 perpendicular type liver cancer portal vein of TTPV can be easily and effectively gripped
Cancer embolus takes bolt to clamp.
The utility model solves the technical scheme that is used of above-mentioned technical problem：A kind of medical perpendicular type liver cancer portal vein
Cancer embolus takes bolt to clamp, including binding clip, tong arm, rivet rotating shaft, spacing sawtooth, handle, and the stage casing of two tong arms is mutual with rivet rotating shaft
Riveted rotates connection, and tong arm rear end is provided with binding clip, the binding clip be connected with tong arm after be in 90 ° of angles, the binding clip have it is preceding it is flat after
The wide flat arc-shaped concave structure of gradual change type, when two tong arms drive binding clip closure, 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 binding clip madial wall is wave camber cone structure, in gripping cancer embolus
When, two binding clip madial wall wave camber cone structures are tightly engaged.
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 between 10-30mm, and tail end height exists
Between 6-12mm, 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, can easily stretch into the blood in 90 ° of shape distributions in vena portae hepatica branch
Pipe, when blood vessel is stretched into binding clip part, binding clip dehisces to accomplish to maximize, and makes single gripping amount big, and cancer embolus is difficult to take off after binding clip closure
Fall.The utility model processing and manufacturing is easy, with low cost, the need for more suiting surgery of liver clinical treatment and easy to operate, real
It is strong with property, 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 perpendicular type liver cancer and portal vein cancer of the present utility model takes bolt to clamp, including binding clip 1, tong arm 2,
Rivet 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 with rivet
The mutual riveted of rotating shaft 3 is connected；When two tong arms 2 drive the closure of binding clip 1, the flat arc of preceding flat rear wide gradual change type of two head ends of binding clip 1
Shape concave surface pairing, formation sealedly takes bolt chamber 6.The madial wall of binding clip 1 is the structure of the conical surface 8 of wave camber 7.When gripping cancer embolus,
The close structure of the conical surface 8 engagement of two madial wall wave cambers 7 of binding clip 1（Fig. 2）.
As shown in Figure 2,3, the head end height a after the engagement of two binding clips is between 2-6mm, length b between 10-30mm,
C is between 6-12mm for tail end height, and 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 5,6, it is in about 90 ° of vessel size according to vena portae hepatica branch in art, using suitably taking bolt to clamp, makes
Flat camber binding clip cambered surface press close to 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, will not
There is the phenomenon that extrudes intravascular cancer embolus inward, now binding clip is dehisced size h maximizations, can smoothly single grip it is the maximum amount of
Thrombus.
Embodiment：
The utility model is cutting off right liver in operation in use, by taking right liver tumour right branch of portal vein branch cancer embolus as an example
After tumour, right branch portal vein is opened, is clamped first by binding clip and tong arm in the cancer embolus at 90 ° of angles, 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 riveting in portal vein
Rotating shaft 3 is followed closely by the opened with certain angle of binding clip 1 to adapt to the size of blood vessel, binding clip stretches into right branch branch vessel, then binding clip 1 is closed
Extract blood vessel mouthful cancer embolus after conjunction out, exhaust the larger cancer embolus of the venous blood mouth of pipe.After the completion of blood vessel mouthful cancer embolus is exhausted, according to vena portae hepatica blood
Pipe branch from the coarse to fine the characteristics of, reuse binding clip head end height 4mm, binding clip length 20mm, binding clip tail end height 8mm, binding clip
Width 8mm cancer embolus pincers, take out vein blood vessel middle-end cancer embolus, finally using binding clip head end height 2mm, binding clip length 10mm, pincers
Tail end height 6mm, binding clip height 6mm cancer embolus pincers, exhaust portal vein end and most carefully locate cancer embolus.
