Abstract

The utility model provides a settling recovery device for a nickel titanium memory alloy esophageal stent used under X-ray fluoroscopy. The settling recovery device structurally comprises an outer sleeve, an inner sleeve, a sampling pincer and the nickel titanium memory alloy esophageal stent, wherein a pincer opening head of the sampling pincer is inserted into the inner sleeve; the inner sleeve is inserted into the outer sleeve; a latex ring sleeves an outer wall at the lower end of the inner sleeve; a horn-shaped handle is arranged at the rear end of each of the outer sleeve and the inner sleeve; the upper end of the nickel titanium memory alloy esophageal stent sleeves the latex ring while the lower end sleeves the lower end of the inner sleeve; a metalized annular tightening line is arranged at one end of the nickel titanium memory alloy esophageal stent. The settling recovery device has the advantages that the structure is simple, the settling recovery device can be settled and recovered, the operation is convenient, the operation time is short, the pain of a patient is light, the labor intensity of doctors is low, the nickel titanium memory alloy esophageal stent after being recovered can be reused, and the treatment cost of the patient is greatly reduced.

Description

The Ultimum Ti Esophageal Stent using under a kind of x-ray fluoroscopy is laid retracting device

Technical field

This utility model relates to technical field of medical instruments, and the Ultimum Ti Esophageal Stent specifically using under a kind of x-ray fluoroscopy is laid retracting device.

Background technology

If there is canceration in human body esophagus, esophagus can be stopped up, cause patient can not swallow food and hungry and dead, in order to extend patient's life, prior art is to lay Ultimum Ti Esophageal Stent by Esophageal Stent setting device at esophagus diseased region esophagus is strutted, expand the intracavity diameter at pathological changes esophagus position, pass through with instant food, the operation of laying of this Esophageal Stent is implemented under gastroscope helps, but the problem existing is, after Ultimum Ti Esophageal Stent is laid, there is a lot of patients' esophageal canceration position again esophagus to be stopped up, cause and swallow food difficulty, through x-ray fluoroscopy, find because of esophageal peristalsis and swallow coarse granule food Ultimum Ti Esophageal Stent is pushed away in stomach, the solution of prior art is to use special shearing apparatus under the help of gastroscope, Ultimum Ti Esophageal Stent to be sheared broken bit by bit, take out one by one by biopsy forceps again, and then lay a new Ultimum Ti Esophageal Stent, perform the operation very complicated, patient is very painful, operation increases doctor's labor intensity for a long time, also increased patient's medical expense, the solution also not had at present.

Summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides the Ultimum Ti Esophageal Stent using under a kind of x-ray fluoroscopy to lay retracting device.

The technical solution of the utility model realizes in the following manner, this Ultimum Ti Esophageal Stent is laid retracting device, comprise trocar sheath, inner sleeve, sample pickup tongs and Ultimum Ti Esophageal Stent, the jaw head of sample pickup tongs interts among inner sleeve, inner sleeve is inserted among trocar sheath, the outer wall cover of inner sleeve front end has latex ring, the rear end of trocar sheath and inner sleeve is provided with horn-like hands handle, the upper end of Ultimum Ti Esophageal Stent is enclosed within on latex ring, lower end is enclosed within the front end of inner sleeve, one end of Ultimum Ti Esophageal Stent is provided with the tight mouthful line of metallization annular,

The described tight mouthful line of metallization annular is to be made up of the chemical fibre of surperficial metal-plated membrane.

Esophageal Stent of the present utility model is laid retracting device and is had following outstanding beneficial effect:

Simple in structure, can lay, also can reclaim, facilitating operation, operating time are short, and patient's misery is little, and doctor's labor intensity is low, and Esophageal Stent is reusable after reclaiming, and can greatly alleviate patient's medical expense.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Ultimum Ti Esophageal Stent of the present utility model is laid retracting device, comprise trocar sheath 5, inner sleeve 4, sample pickup tongs 3 and Ultimum Ti Esophageal Stent 1, the jaw head of sample pickup tongs 3 interts among inner sleeve 4, inner sleeve 4 is inserted among trocar sheath 5, the outer wall cover of inner sleeve 4 front ends has latex ring 7, the rear end of trocar sheath 5 and inner sleeve 4 is provided with horn-like handle 6, the upper end of Ultimum Ti Esophageal Stent 1 is enclosed within on latex ring 7, lower end is enclosed within the front end of inner sleeve 4, and one end of Ultimum Ti Esophageal Stent 1 is provided with the tight mouthful line 2 of metallization annular;

Embodiment 1

It is as follows that Ultimum Ti Esophageal Stent is laid surgical operation step:

1) first inner sleeve is inserted in trocar sheath, allow and expose from trocar sheath with one end of latex ring, the upper end of Ultimum Ti Esophageal Stent freezing after shrinking is enclosed within on the latex ring of inner sleeve lower end, again Ultimum Ti Esophageal Stent is together filled among trocar sheath together with latex ring, then the inner sleeve handle of pulling back, latex ring traction Ultimum Ti Esophageal Stent all enters among trocar sheath for subsequent use;

2) while operation, first with contrast agent to pathological tissues radiography, under the supervision of X-ray machine, the retracting device of laying that Ultimum Ti Esophageal Stent is housed is sent Ultimum Ti Esophageal Stent into esophagostenosis position from patient oral cavity, then with latex ring on inner sleeve, Ultimum Ti Esophageal Stent is released from trocar sheath, Ultimum Ti Esophageal Stent leaves after trocar sheath, the bulk expansion of being heated is returned freezing front shape esophagostenosis place is strutted, extract trocar sheath and inner sleeve, it is complete that Ultimum Ti Esophageal Stent is laid operation;

Embodiment 2

It is as follows that Ultimum Ti Esophageal Stent reclaims surgical operation step:

1) first with contrast agent to pathological tissues radiography, under the supervision of X-ray machine, trocar sheath is inserted to patient's stomach near the Ultimum Ti Esophageal Stent coming off, sample pickup tongs is vised to the tight mouth of metallization annular line from middle insertion of trocar sheath, be drawn among trocar sheath, then extract trocar sheath, take out Ultimum Ti Esophageal Stent;

2) the Ultimum Ti Esophageal Stent taking out is carried out to integrity inspection, if intact, then under the supervision of X-ray machine, again lay surgical operation step by Ultimum Ti Esophageal Stent Ultimum Ti Esophageal Stent is put back to assigned address.

Except the disclosed technical characterictic of description of the present utility model, be the known technology of those skilled in the art.
