Description
Technical field
The present invention relates to medical instruments fields, more particularly, to a kind of operation handle and medical adjustable bending sheath tube.
Background technique
Currently, intervention operation is usually required by mediatory type diagnosis and treatment sheath (such as guiding sheath, delivery sheath, guiding catheter
Deng) channel of Lai Jianli patient's body diseased region and external operation end, to import various medical instruments, drug, implantation instrument
Deng the diseased region to patient, achieve the purpose that avoid using the i.e. reachable diseased region of surgical operation.Mediatory type diagnosis and treatment sheath
It is generally made of sheath tube body with the operation handle for installing the sheath tube body, sheath tube body is longer and has interior as channel
Chamber, sheath tube body have proximally and distally, distally can be convenient into body lumen (such as blood vessel), proximal end is then used for attended operation
Handle is used for health care professional.In intervention operation, medical staff needs under the guidance of X-ray machine, by vitro to behaviour
The distal end of sheath tube body is sent to predetermined position by the operation for making handle.
To be adapted the anatomic morphological of sheath body distal end and specific diseased region, people are different according to sheath purposes
And the distal end preformed of sheath tube body is formed into different curved shapes, however, even having developed various shape and angle
Distally pre- moulding intervenes class diagnosis and treatment sheath, following situations is also frequently occurred in clinical use: the distal end of various shape and angle
Pre- plastotype sheath can not also adapt to one by one with the physiological anatomic architecture of individuation, when occurring problems in operation, Yi Shengtong
Sheath can often be withdrawn to and be selected again the pre- plastotype sheath of other shapes, will so improve the consumption increase patient that performs the operation and be undertaken
Expense, also increase the probability that the lumen cavity tissue of sufferer is damaged, extend operating time to extend patient's raying
Time etc..The pre- moulding intervention class diagnosis and treatment sheath in the distal end of various shape and angle, which is put to, clinically to be used.This requires doctors
Institute must get all the shape and specification of all sheaths ready, undoubtedly increase the stock model and quantity of hospital, increase hospital at
This.Based on the above circumstances, sheath distal end adjustable bending technology is developed in recent years, and the medical adjustable bending sheath tube of the technical application passes through
External adjusting operation changes the distal end of sheath tube body repeatedly between different angle, to be adapted to different Physiological Anatomy
Form.
Medical adjustable bending sheath tube in the prior art include operation handle, the sheath tube body being installed in operation handle and
Adjust curved silk;Wherein, operation handle is mostly branch type, including main branch and collateral, and the distal end of curved silk and the distal end of sheath tube body is adjusted to connect
Connect, adjust the proximal end of curved silk from the side wall close to proximal end of sheath tube body wear out after pass through handle it is collateral and be arranged in handle side
Lock control sliding block connection in branch is pulled or is loosened by lock control sliding block and adjusts curved silk with the adjustable curved segment in the distal end for changing sheath tube body
Curved shape, but lock control sliding block must be controlled with hand.Since the main branch of branch type handle does not provide the position of holding, together
When main branch and side branch outer dimension it is thinner and shorter and smaller, be unsuitable for hand-held operation, in use, medical staff need to hold it is adjustable
Curved sheath handle simultaneously applies certain thrust, holds main branch on the other hand, another manual control lockmaking control sliding block, and use is very inconvenient.
In addition, the inside of operation handle is generally fitted with gas deflation assembly in medical adjustable bending sheath tube in the prior art,
Gas deflation assembly includes exhaust part, and exhaust part has discharge chamber, and the proximal end of sheath tube body is connected to the distal end of discharge chamber, in discharge chamber
Proximal end on the hemostasis valve deck of proximal end for closing discharge chamber is installed;In use process, need to discharge chamber to liquid, punching row
The distal end of sheath tube body is sent to predetermined position again after the air of sheath tubular body out, ensures that sheath tube body enters human body with this
Without gas in interior part pipe, and then guarantee that surgical work is gone on smoothly.But in the prior art, hemostasis valve deck is not easy to install,
And hemostasis valve deck be installed on the proximal end of discharge chamber after easily with respect to exhaust part slide to cause hemostasis valve deck loosen or fall off.
In conclusion medical adjustable bending sheath tube in the prior art, which exists, adjusts curved inconvenient, gas deflation assembly installation place haemostatic valve
It covers after not easy to install and hemostasis valve deck is installed on the proximal end of discharge chamber and rotates to cause hemostasis valve deck easily with respect to exhaust part
The problems such as loosening or falling off.
