Description
Technical field
The utility model is related to a kind of surgery to puncture sheath expander, belongs to technical field of medical instruments.
Background technology
With developing rapidly for modern medicine, cardiovascular surgical procedure and intubation intervention operation are clinically achieved extensively
Application, both respectively have quality.Surgical operation indication is wide, but has the shortcomings that cardiac arrest, wound are big；Intubation intervention hand
Art without extracorporal circulatory system, wound be small, recovery is fast, however it is necessary that using radioactive ray and contrast agent.Surgery intervention operation controls two kinds
Treatment method is combined together, and gives full play to both advantages, not only without extracorporal circulatory system, wound be small, recovery is fast, also without radiation
Line, contrast-agent-free allergy, without peripheral vascular damage equivalent risk.Current surgery intervention operation has been obtained extensively in the world
Carry out, surgery therein intervention operation is mainly used in congenital heart disease Occlusion therapy, through aorta pectoralis valve balloon dilatation, lung
Arterial valve narrow rack implantation and aorta arch constriction stent endoprosthesis etc., its outstanding feature are exactly minimally invasive and safe.Outward
Section's intervention operation is applied to congenital heart disease Occlusion therapy, and the age limit of patient and body weight limitation will all be reduced, and accomplish early discovery, morning
Treatment；Chest surgical incision only there are about 2cm, it is not necessary to use blood transfusion in extracorporal circulatory system and art；One-stop treatment, occurs in operation
Fortuitous event, can at any time be switched cardiac operation under direct vision, percutaneous intervention operation, surgery intervention operation Three models；Outward
Section intervenes operation no radiation, contrast-agent-free, the damage without peripheral vascular.
In surgery intervention operation, widely used is implemented through the small otch of chest, and the mini-incision through about 3cm under breastbone enters
Enter vertical diaphragm, after cutting pericardium and suspend pericardium in midair using scalpel, you can open-heart, be operated.Pericardium is heart
One layer of connective tissue membrane structure that periphery is tightly wrapped up, heart wall is made up of cardiac muscle.In surgical procedure, typically using scalpel
Pericardium and cardiac muscular tissue are cut, the path that catheter sheath enters heart is opened, so that apparatus can smoothly lead in subsequent procedures
Cross sheath and enter lesion.Which still needs to carry out suture cardiac muscle and pericardial tissue after treatment is completed, leave wound compared with
Greatly, postoperative to need indwelling drainage tube, rehabilitation is slower, and postoperative cavum pericardiale can stick together, and patient's pain time is long.
The content of the invention
The technical problems to be solved in the utility model is：Sheath enlargement of pipe is punctured there is provided a kind of surgery for reducing treatment time
Device, to solve and cut pericardium and cardiac muscular tissue using scalpel so that pipe sheath is into causing treatment time long by the way of heart, art
The slow problem of rehabilitation afterwards.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of surgery and puncture sheath enlargement of pipe
Device, it is characterised in that including pipe shaft, the two ends of pipe shaft connect piercing distal end and near-end base respectively, and piercing distal end is in metal
Empty pyramidal structure.
Preferably, described piercing distal end is a hollow metal needle-like head.
Preferably, the angle between the axial direction of the spot face of described piercing distal end and pipe shaft distal end is 30 ° -60 °.
Preferably, the pipe shaft near-end of described pipe shaft is provided with scale mark.
Preferably, formed between described pipe shaft and piercing distal end and seamlessly transitted.
Preferably, described pipe shaft is provided with bent angle, and the angular range of bent angle is 100 ° -160 °.
The utility model is applied in the operation of surgery congenital heart disease, it is to avoid the use scalpel of prior art cut pericardium and
There is piercing distal end cardiac muscular tissue, front end of the present utility model, and piercing distal end is metal hollow pyramidal structure, can will puncture and lead
Pipe insertion process merges one, can Direct perforantes enter heart, for aiding in setting up passage, convey various plugging devices to lesion
Discharged, reduced artificial operation, reduced treatment time, reduced patient's pain and accelerate rehabilitation, it is mainly used in respectively
The surgery Transcatheter Closure of class congenital heart disease；Pipe shaft carries out mark, and doctor can judge rollback distance according to scale.

Specific embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The utility model is expander used during a kind of surgery intervention is performed the operation, for carrying out surgery through the small otch hand of chest
Art, through the puncture sheath of the medicine equipments such as pericardium conveying plugging device.
The utility model is that a kind of surgery punctures sheath expander, as shown in figure 1, the expander includes piercing distal end 1, pipe
Body 2 and near-end base 3, the two ends of pipe shaft 2 connect piercing distal end 1 and near-end base 3 respectively.
There is mark to design (being provided with scale mark on pipe shaft near-end) with the junction of near-end base 3 on pipe shaft 2, such as Fig. 4
Shown, doctor can control piercing distal end 1 to stretch out the depth of outer tube 4 by scale, and judge rollback distance according to scale,
Facilitate the operation of doctor.
As shown in figure 3, piercing distal end 1 is metal hollow pyramidal structure, the spot face of piercing distal end 1 and the distal end of pipe shaft 2
Axial direction between angle be 30 ° -60 °.
Piercing distal end 1 is a hollow metal needle-like head；Pipe shaft 2 is macromolecular material, by injection molding manner, can be with metal
Piercing distal end 1 is linked together, and the linkage section is seamlessly transitted；Convex stripe is designed on near-end base 3, doctor can be facilitated to hold.
As shown in figure 5, expander of the present utility model 5 needs to be used cooperatively with outer tube 4 in surgical procedure, at cooperation
Seamlessly transit, the distance that expander 5 stretches out outer tube 4 is 5-10mm, in surgical procedure, the chambers of the heart entered by puncture together,
After the completion of puncture action, expander 5 can be retracted and withdrawn from, piercing distal end 1 is retracted to outer tube 4, prevent it from puncturing remote
Hold 1 injury tissue.Retain outer tube 4 and the path that apparatus passes through is constituted in the chambers of the heart.Outer tube 4 is existing at present quite ripe extensive
Application.
As shown in Fig. 2 front end have curved expander can according to operation diseased region physiology anatomical features, in pipe shaft
Suitable bent angle is selected on 2, the insertion of sheath is more beneficial for, bent angle scope is 100 ° -160 °.
