Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

In the various drawings of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration and, therefore, are used only to illustrate the basic structure of the subject matter of the present invention.

As shown in FIG. 1, the present invention provides an anorectal endoscope 10, which comprises a holding part 11 and an endoscope body part 12. Wherein, the holding part 11 is used for holding and operating the anorectal endoscope 10 by medical staff, and the endoscope body part 12 is used for inserting into anorectum.

The grip member 11 includes a grip 111 and a first connecting portion connected to the grip 111. The grip 111 is an area to be gripped by medical staff, and may be provided in a shape convenient for gripping.

The scope body part 12 includes a scope body 121, a stopper 122, and a second connecting portion. The scope body 121 is a portion of the scope body part 12 for insertion into the anorectum. The blocking part 122 is connected to the endoscope body 121, the outer diameter of the blocking part 122 is larger than that of the endoscope body 121, and after the endoscope body part 12 is inserted into the anorectum, the blocking part 122 is at least partially positioned outside the human body to prevent the endoscope body part 12 from being inserted into the human body too deeply.

The second connecting portion is connected to one side of the blocking portion 122 departing from the lens body 121, and the first connecting portion is detachably connected to the second connecting portion. When the first connecting part and the second connecting part are connected, the mirror body part 12 is fixed relative to the holding part 11, and at the moment, the medical staff can carry out anorectal examination by holding the holding part 11.

When the anorectal region needs to be checked, the medical staff connects the first connecting part and the second connecting part, so that the endoscope body part 12 and the holding part 11 are installed together, and then the endoscope body part 12 is inserted into the anorectal region. After the examination is completed, the medical staff detaches the first connecting part and the second connecting part, and then directly discards the mirror body part 12 and replaces the mirror body part 12 with a new one. The disposable lens body part 12 does not cross-infect and has no trouble of disinfection and cleaning. The blocking portion 122 can prevent the lens body 12 from being inserted too deeply and can block the intestinal contents from flowing out, so that the holding member 11 is not easily contaminated.

As shown in fig. 2 and 3, in one embodiment of the present invention, the grip 11 further includes an unlocking member 112 and a resilient releasing member 113. The unlocking member 112 is used to unlock the first and second coupling portions, thereby making the grip part 11 and the scope part 12 separable. The elastic release 113 automatically separates the mirror body part 12 from the grip part 11 by pushing the second coupling part after the first coupling part and the second coupling part are unlocked.

The handle 111 is provided with a corrugated structure for the medical staff to hold, and the unlocking piece 112 is installed on the handle 111 and located below the corrugated structure, so that the medical staff can press the unlocking piece 112 with fingers to trigger the unlocking piece 112.

The elastic buckle 124 includes an elastic arm 1241 and a buckling protrusion 1242 disposed on the elastic arm 1241, the bottom end of the elastic arm 1241 is connected to the top wall or the bottom wall of the groove, and an avoiding gap 125 is formed between the side wall of the groove and the elastic arm 1241 to avoid the elastic arm 1241 when the elastic arm 1241 deforms. When the elastic buckle 124 is matched with the bayonet 115, the buckling protrusion 1242 extends into the bayonet 115 and abuts against the bottom wall of the bayonet 115.

The unlocking member 112 unlocks the first and second connection parts by separating the elastic catch 124 from the bayonet 115 by pushing the elastic catch 124.

Specifically, the unlocking member 112 is disposed outside the receiving cavity 114, and a cavity is disposed inside the handle 111 for receiving the receiving part to disassemble the locking member 112 and allow the unlocking member 112 to move. The unlocking member 112 has a holding portion 1121 and a button 1122 connected to each other. The supporting portion 1121 is movably disposed to enter or leave the bayonet 115, so as to push the fastening protrusion 1242 in the bayonet 115 to move, thereby unlocking the first connecting portion and the second connecting portion. Button 1122 extends outside of handle 111 to facilitate the operation of unlocking member 112 by the medical professional. The button 1122 drives the abutting portion 1121 to move when receiving an external force, thereby triggering the unlocking member 112 to unlock the first connecting portion and the second connecting portion.

As shown in fig. 4 and 5, in a preferred embodiment, the inner wall of the receiving cavity 114 is provided with a positioning strip 13, the embedded portion 123 is provided with a positioning groove 14 matched with the positioning strip 13, and the positioning groove 14 extends to the top end of the embedded portion 123 to form an opening so that the positioning strip 13 can be inserted into the positioning groove 14. Or, as shown in fig. 6 and 7, the side surface of the embedding portion 123 is provided with a positioning strip 13, the interior of the accommodating cavity 114 is provided with a positioning groove 14 matched with the positioning strip 13, and the positioning groove 14 extends to the bottom end of the handle 111 to form an opening, so that the positioning strip 13 is inserted into the positioning groove 14. When the first connecting portion and the second connecting portion are assembled, the positioning bar 13 slides relative to the positioning groove 14 along the extending direction of the positioning groove 14, so that the movement of the first connecting portion or the second connecting portion is guided, and the mirror body part 12 is prevented from rotating and shaking in the assembling process and after the assembling is completed.

The resilient release member 113 is disposed within the receiving cavity 114. The elastic release member 113 is a spring, an air bag, or the like having elasticity. The top wall of the receiving cavity 114 abuts against the top end of the resilient release member 113. When the first connecting portion is connected to the second connecting portion, the bottom end of the elastic releasing member 113 abuts against the embedding portion 123 and the elastic releasing member 113 is in a compressed state. When the unlocking piece 112 unlocks the first connecting part and the second connecting part, the elastic releasing piece 113 pushes the second connecting part to move downwards, so that the mirror body part 12 is automatically separated from the holding part 11.

The anorectal endoscope 10 of the above embodiment needs to connect the holding part 11 and the endoscope body part 12 together, and after aligning the first connecting part and the second connecting part, the holding part 11 and/or the endoscope body part 12 are moved linearly, so that the connection between the holding part 11 and the endoscope body part 12 can be completed, the anorectal endoscope 10 is simple and convenient to operate, and the detection efficiency is improved.
