Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and are not construed as limiting the present application.

Aiming at the problem that a guide device for guiding surgical instruments such as internal diameter and the like to go deep into the thoracic cavity is lacked in the prior art, please refer to fig. 1 and 2, the application provides a guide sheath 1 for a single-hole endoscopic instrument, which is suitable for a puncture sheath tube in a thoracoscopic operation and is convenient for an operator to operate and use.

The single-hole endoscope instrument guide sheath 1 comprises an outer sheath tube 11, a connecting rod 12 and a handle 13, wherein the outer sheath tube 11 is in a ring-shaped tube shape and can be used for inserting instruments to play a guiding role, meanwhile, an opening 111 extending along the axial direction of the outer sheath tube 11 is formed in the outer sheath tube 11, and an endoscope puncture sheath 2 can be separated from the single-hole endoscope instrument guide sheath 1 from the opening 111. The connecting rod 12 is connected with one side of the outer sheath 11 far away from the opening 111, and the connecting rod 12 is provided as a flexible piece to enable the relative position of the outer sheath 11 and the handle 13 to be adjustable, so that the angle of the handle 13 can be adjusted by bending the connecting rod 12, and mutual interference between instruments is avoided.

Preferably, the radial cross section of the outer sheath 11 with the opening 111 is a 3/4 circular arc structure, and the outer sheath 11 is made of a metal sheet with elasticity, so that the outer sheath 11 can be buckled on the endoscope body of the endoscope, and the endoscope puncture sheath is squeezed to separate from the outer sheath 11 from the opening 111 of the outer sheath 11 due to the good elasticity of the outer sheath 11. In addition, the arc diameter of the outer sheath tube 11 of the present invention is adapted to the size of the endoscopic instrument, and in the present embodiment, if the operation is performed using an endoscope with a 5mm puncture sheath, the arc diameter of the outer sheath tube 11 in the present embodiment is 5mm, and the distance between the end side of the outer sheath tube 11 located at the opening 111 and the end side thereof opposite to the opening 111 is 4mm. In addition, for different sizes of medical instruments, the outer sheath tubes 11 with different circular arc diameters can be selected to be matched with the medical instrument for operation.

Further, the front end of the outer sheath tube 11 is also provided with a tip, so that the sheath tube can be conveniently inserted into the chest cavity of a patient along the endoscope.

Connecting rod 12 adopts the diameter to make for 2 mm's metal pole, and the diameter has flexibility and toughness can realize crooked for 2 mm's metal pole, thereby can realize the regulation of relative position between sheath pipe 11 and the handle 13 avoids handle 13 to produce the interference to other medical instrument, better the implementation that does benefit to the operation.

In this embodiment, the length of the outer sheath 11 is 3cm, the length of the connecting rod 12 is 2cm, and the length of the handle 13 is 6cm, that is, the size of the guide sheath 1 for the single-port endoscopic instrument is small, so that the interference to other surgical instruments can be avoided. The single-hole endoscope instrument guiding sheath 1 is made of metal materials, simple in structure and convenient for cleaning and disinfecting by medical staff.

Referring to fig. 3, the present application further relates to an endoscope puncture sheath 2, which includes a sheath tube 21 and a rubber valve seat 22, the rubber valve seat 22 is disposed at one end of the sheath tube 21, an air outlet (not shown) is disposed at the other end of the sheath tube 21 far away from the rubber valve seat 22, and an air inlet pipe 221 is further disposed on the rubber valve seat 22. Meanwhile, the endoscope puncture sheath 2 further comprises the single-hole endoscope instrument guide sheath 1, and the single-hole endoscope instrument guide sheath 1 is buckled in the sheath tube 21 through the sheath tube 11 to realize connection of the single-hole endoscope instrument guide sheath and the sheath tube.

Furthermore, the end of the sheath tube 21 away from the rubber valve seat 22 is a flat head, so that the injury of the tip to the organ tissue in the cavity can be avoided.

In addition, the length of the sheath tube 21 in the embodiment is shortened to 8cm, and meanwhile, the volume of the rubber valve seat 22 is reduced compared with the volume of the existing valve seat, so that the interference of the endoscope puncture sheath 2 on other surgical instruments is reduced by reducing the valve seat and shortening the sheath tube 21, and the surgical operation is facilitated.

The application of the single-hole endoscope instrument guide sheath 1 and the endoscope puncture sheath 2 is as follows:

when an operation is performed, the outer sheath tube 11 of the single-cavity endoscope instrument guiding sheath 1 can be buckled on the sheath tube 21 of the endoscope puncturing sheath 2, then the single-cavity endoscope instrument guiding sheath 1 can be pushed into a chest cavity of a patient along the sheath tube 21, and if the endoscope puncturing sheath needs to be replaced or other surgical instruments need to be inserted, the sheath tube 21 of the endoscope puncturing sheath 2 can be separated from the outer sheath tube 11 from the opening 111 of the outer sheath tube 11, so that the separation of the single-cavity endoscope instrument guiding sheath 1 and the endoscope puncturing sheath 2 is realized. Meanwhile, the sheath tube 11 is retracted to the chest wall, and the instrument channel constructed by the arc-shaped structure of the sheath tube 11 can be used for facilitating the entry and exit of other medical instruments, so that the operation process is accelerated. Meanwhile, the single-hole endoscope instrument guide sheath 1 can also be used as an auxiliary surgical instrument to push and block lung tissues so as to help an operator to expose the lung tissues to the visual field.

In conclusion, the single-hole endoscope instrument guide sheath 1 of the present application is provided with the outer sheath tube 11 having the opening 111, so that when the endoscope puncture sheath 2 of the present application is used, different surgical instruments are replaced or placed without extending or opening the incision, thereby facilitating the operation and use of the operator. Meanwhile, the flexible connecting rod 12 is arranged between the outer sheath tube 11 and the handle 13, so that the relative position of the outer sheath tube 11 and the handle 13 can be adjusted, and the handle 13 is prevented from interfering other medical instruments.

The foregoing is only a partial embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations should also be regarded as the protection scope of the present application.
