Description

Puncture reducing laparoscope puncture outfit with protective sleeve

Technical Field

The utility model relates to a laparoscope puncture outfit.

Background

The laparoscope puncture outfit is disposable, is suitable for gas delivery in minimally invasive surgery and the establishment of a channel for an endoscope and surgical instruments to enter and exit a body cavity from the outside, is suitable for various laparoscopic surgeries, including surgical minimally invasive surgery, gynecological minimally invasive surgery, thoracic surgery, urinary surgery and other laparoscopic surgeries, and can be matched with various laparoscopic television systems at home and abroad.

Although the laparoscopic puncture instrument is minimally invasive, scars are left on the human body to affect the appearance, so that the puncture times and holes need to be reduced as much as possible. In addition, because human tissues have good toughness, in order to achieve a minimally invasive effect and an attractive effect, the wound of a patient is very small, so that skin tissues can generate very large resistance when a doctor punctures, and the difficulty of surgical puncture is greatly increased. In clinical operation, the laparoscope puncture outfit has good sharpness when puncturing the skin, so as to ensure smooth puncture of doctors, and simultaneously, the laparoscope puncture outfit must ensure that the visceral tissues of the human body are not punctured at the moment of completing puncture.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a take subtract hole peritoneoscope puncture ware of protective sheath, its sleeve can hold two operating means and get into simultaneously, has reduced the quantity of puncture number of times and puncture hole. Meanwhile, the sharp end for puncture can be shielded by the protective sliding sleeve at the moment of completing puncture, so that the viscera can be prevented from being punctured (cut).

In order to solve the technical problem, the technical scheme of the utility model is to adopt a puncture reducing laparoscope puncture outfit with a protective sleeve, which comprises a sleeve and a rod-shaped inner core inserted in the sleeve; the top end of the sleeve is provided with a sleeve seat, and an air inlet valve is mounted on the sleeve seat; the top end of the inner core is provided with a top cover used for being connected with the sleeve seat, and the lower end of the inner core is a sharp end used for puncture; the cross section of the sleeve is oval, and the cross section of the rod part of the inner core is matched with that of the sleeve; an annular groove is formed in the lower end of the rod part, located outside the tip end, a protective sliding sleeve is arranged in the groove and can slide up and down along the groove; a driving spring for ejecting the protective sliding sleeve outwards is arranged above the protective sliding sleeve in the groove; the inner core is hollow, an axial core bar is arranged in the inner core, and the core bar can slide up and down along the inner core; the lower end of the core rod is provided with a spring plate, the side wall of the protective sliding sleeve is provided with a positioning hole, and the spring plate can extend into the positioning hole to clamp the protective sliding sleeve; a return spring is arranged below the core rod, and a top cover extends out of the top end of the core rod. The utility model discloses owing to done and subtract the hole design, get into in order to hold two operation tools simultaneously, carry out a plurality of increasements to telescopic hole. In order to make the puncture smoothly, the tip thereof needs to be sharper. When puncturing is carried out, the positioning hole which is separated from the protective sliding sleeve is retracted by pressing the core rod, so that the protective sliding sleeve can move freely. In the process of puncture, the core rod is released, and the protective sliding sleeve is retracted all the time to expose the tip due to the resistance of human tissues. When the tip punctures the abdominal cavity of the human body, the resistance disappears, the protective sliding sleeve is rapidly ejected out under the action of the driving spring to shield the tip, and the elastic sheet is clamped into the positioning hole, so that the protective sliding sleeve can not retract even if contacting with the viscera at the moment.

As an improvement, the end part of the elastic sheet is provided with a positioning block. Through the locating piece and the locating hole cooperation location on the protective sliding sleeve for the protective sliding sleeve is difficult to return back.

As a further improvement, the positioning block is a right triangle, the right angle side of the positioning block faces downwards, and the inclined side of the positioning block faces upwards. The arrangement makes the protective sliding sleeve not retract and not block the ejection.

As another further improvement, the elastic sheet and the axis of the core rod form an acute angle. When the core rod is pressed, the elastic sheet is very easy to be driven to be inwardly folded to be separated from the range of the positioning hole, and the protective sliding sleeve cannot be pushed back due to different stress directions when being pushed back.

As an improvement, the number of the elastic sheets is two, namely a left elastic sheet and a right elastic sheet, and the number of the positioning holes in the protective sliding sleeve is also two. Keeping stability and avoiding single side.

As an improvement, the length of the protective sliding sleeve extending out of the inner core is greater than that of the tip. The tip is ensured to be within the protection range of the protective sliding sleeve.

As an improvement, the long axis of the oval inner hole of the sleeve is 1.5 cm, and the short axis of the oval inner hole of the sleeve is 0.75 cm. Such that the sleeve can accommodate two surgical instruments to be operated simultaneously.

As an improvement, the tip of the inner core is a cross-shaped blade. The tissue is convenient to cut, and the puncture difficulty is reduced. Because the existence of protective sheath, can set up very sharp with the point end without worry, and the general point end of current puncture ware is comparatively blunt, mainly avoids the accidental injury.

The utility model discloses an useful part lies in: the laparoscopic puncture outfit with the structure increases the cross-sectional area of the sleeve, so that the laparoscopic puncture outfit can simultaneously accommodate two surgical instruments for operation. The puncture frequency and the number of puncture holes are reduced, the pain of the patient is relieved, and the appearance is more attractive. Meanwhile, the protective sliding sleeve is arranged at the tip of the inner core, so that the tip can be shielded at the moment when the puncture enters the abdominal cavity, the internal organs are prevented from being cut or punctured, and the occurrence probability of medical accidents is greatly reduced.
